DIN 1897 Drill: Stub Drill Bit Standard, Sizes and Wholesale Sourcing Guide

Wrong drill length can cost you repeat orders.

For importers, wholesalers, tool distributors, and procurement managers, a drill bit is not just a small cutting tool. It is part of your product reputation. If the drill bends, walks on the surface, breaks too early, or produces inaccurate holes, your customers will not complain about the factory. They will complain about your brand.

This is why the DIN 1897 drill matters.

If you source drill bits in bulk, understanding DIN 1897 is not only a technical issue. It helps you reduce wrong purchases, control quality complaints, choose the right material grade, and build a more professional product line for your market.

What Is a DIN 1897 Drill?

A DIN 1897 drill is a short-series twist drill made according to the DIN 1897 dimensional standard. It is mainly used for drilling shallow holes where high rigidity and reduced deflection are required.

In the market, you may see DIN 1897 drill bits described as:

• DIN 1897 stub drill bits
• Screw machine length drill bits
• Extra short HSS drill bits
• Short HSS twist drills for metal

The main feature of a DIN 1897 drill is its short overall length. Because the drill is shorter, it has better resistance against bending. This help the drill stay more stable during drilling, especially used on metal sheets, thin steel, and automated machines.

For your customers, this means cleaner holes, better control, and less drill walking. For your business, it means fewer complaint and stronger confidence in repeat orders.

Why Short Length Matters

A longer drill bit can reach deeper positions, but it is also easier to bend.¹ When the drill bends, the hole may become oversized, inaccurate, or off-center. In some cases, the drill may even break.

DIN 1897 drill bits solve this problem by using a shorter and more rigid design. This is why they are often chosen for machine drilling, tapping preparation, sheet metal work, and production lines where stability is more important than drilling depth.

Why DIN 1897 Drill Bits Matter for Importers and Wholesalers

When you buy drill bits in bulk, your real concern is not only the unit price. You also need to consider product stability, customer feedback, market positioning, and after-sales risk.

A low-cost drill bit may look attractive at first. But if the geometry is unstable, the hardness is incorrect, or the drill length does not match the application, the hidden cost can be much higher.

Why B2B Buyers Like DIN 1897 Drill Bits

DIN 1897 drill bits² are suitable for wholesalers and importers because they can be sold to many market channels:

• Industrial tool distributors
• Hardware wholesalers
• Metalworking supply stores
• Automotive repair tool suppliers
• Maintenance tool brands
• CNC and machining accessory suppliers
• Private label drill bit sets
• Professional hand tool and power tool accessory ranges

For procurement managers, this product is also easy to organize into different grades. You can offer economy, standard, professional, and premium series based on material, coating, point angle, packaging, and application.

DIN 1897 vs DIN 338 vs DIN 340 vs DIN 1869

One major reason customers search for din 1897 drill is that they want to understand how it is different from other DIN drill standards.

The most common comparison is between DIN 1897, DIN 338, DIN 340, and DIN 1869.

When to Choose DIN 1897

Choose DIN 1897 drill bits when your market needs short, stable, and accurate drilling³. They are a good choice for thin metal, shallow drilling, machine use, and situations where drill rigidity is important.

When to Choose DIN 338

Choose DIN 338 drill bits for general-purpose drilling. DIN 338 is one of the most common twist drill standards and is suitable for many metalworking and maintenance applications.

When to Choose DIN 340 or DIN 1869

Choose DIN 340 or DIN 1869 when your customer needs longer reach or deeper holes. However, longer drills require better control because they are more likely to bend or vibrate.

For a complete drill bit product line, many wholesalers stock DIN 1897, DIN 338, and DIN 340 together. This gives customers a clear choice based on working depth and application.

Common DIN 1897 Drill Sizes and Dimensions

DIN 1897 drill bits are available in many metric sizes. The exact size range depends on the supplier, market, and packaging style. Common wholesale sizes usually cover small to medium diameters for metal drilling.

Typical sizes include:

For bulk purchasing, the most important point is not only whether the diameter is available. You should also confirm the flute length, total length, tolerance, shank diameter, point angle, and surface finish.

What Procurement Teams Should Check

Before placing a bulk order, your inquiry should include:

• Diameter range
• Required standard: DIN 1897
• Material grade
• Point angle
• Surface finish
• Packaging style
• Quantity per size
• Target application
• Target market level

This helps the factory quote correctly and avoid misunderstanding⁴ between economy-grade and professional-grade products.

Which Materials Are Best for DIN 1897 Drill Bits?

Material selection has a direct impact on cutting performance, price level, and market positioning. If you are selling to different customer groups, you should not use one material grade for every market.

A professional DIN 1897 drill line can be divided into different grades.

HSS 4241 for Price-Sensitive Markets

HSS 4241 can be used for markets where price is the main concern. It is suitable for light-duty applications, soft metals, plastic, and general retail demand. However, it is not the best choice for professional stainless steel drilling⁵.

HSS 4341 for General Wholesale

HSS 4341 is a common option for general-purpose drill bit orders. It offers better hardness than entry-level material and can be used for many standard metal drilling applications.

HSS 6542 / M2 for Professional Users

HSS 6542, also known as M2 high-speed steel in many markets, gives better wear resistance and cutting stability. It is more suitable for professional tool distributors and industrial users.

M35 and M42 for Premium Applications

M35 and M42 cobalt drill bits are designed for tougher drilling conditions. They perform better under heat and are more suitable for stainless steel, harder steel, and demanding production environments.

For importers and wholesalers, material grade is also a branding decision. If your customers are professional users, a higher-grade material can reduce complaints and support better margins.

118° or 135° Split Point: Which One Should Buyers Choose?

Point angle is another important detail when sourcing DIN 1897 drill bits. Many buyers focus on material and coating, but point geometry also affects drilling performance.

The two common choices are 118° and 135° split point.

118° Point

A 118° point is widely used for general-purpose drilling.⁶ It is cost-effective and suitable for many basic applications. If your market needs affordable drill bits for general retail and hardware stores, this can be a practical option.

135° Split Point

A 135° split point helps the drill start more accurately. It reduces walking on the workpiece and is more suitable for metal drilling. For DIN 1897 drill bits, this is especially useful because the short body and split point work together to improve stability.

For professional buyers, 135° split point DIN 1897 drill bits are often easier to position as higher-value products.

Surface Finish Options for DIN 1897 Drill Bits

Surface finish affects appearance, rust resistance, lubrication, wear resistance, and shelf appeal. When you build a wholesale product line, surface finish should match your target market.

Bright Finish

Bright finish drill bits are common and cost-effective. They are suitable for general wholesale markets where price control is important.

Black Oxide

Black oxide improves surface protection and helps reduce friction. It is a popular choice for industrial drill bits and maintenance markets.

TiN Coating

TiN-coated drill bits have a gold appearance and better wear resistance. They are often used for premium packaging and branded product lines.

Black and Gold Finish

Black and gold drill bits are popular in retail markets because they look more professional on shelves⁷. For private label brands, this finish can help improve product value without changing the basic drill structure.

Where Are DIN 1897 Drill Bits Used?

DIN 1897 drill bits are not designed for every drilling job. Their strongest advantage is stability in shallow drilling. This makes them useful in many professional applications.

Common applications include:

• Sheet metal drilling
• Thin steel drilling
• Automatic lathe drilling
• Turret lathe use
• CNC machining
• Automotive repair
• Maintenance workshops
• Pilot hole drilling
• Tapping hole preparation
• Confined space drilling
• Production line metalworking

Sheet Metal and Thin Steel

When drilling thin metal, a long drill can walk or vibrate. A DIN 1897 stub drill gives better control and helps produce cleaner holes.

Automatic Machines and CNC Work

In machine drilling, stability is very important. The short length of DIN 1897 drill bits helps reduce deflection and improves repeatability.

Maintenance and Repair Markets

For maintenance users, DIN 1897 drill bits are useful when working in limited space or when better drill control is needed.

Tapping Hole Preparation

Accurate hole size is important before tapping. If the drilled hole is inaccurate, the thread quality may be affected. DIN 1897 drills can help improve hole control in shallow tapping preparation.

When Should You Not Use DIN 1897 Drill Bits?

A professional supplier should not claim that one drill bit can solve every problem. DIN 1897 drill bits are excellent for short and stable drilling, but they are not the best choice for deep-hole applications.

You should not recommend DIN 1897 drill bits when the user needs:

• Deep holes
• Long reach drilling
• Thick material drilling in one pass
• Drilling through deep structures
• Flexible access in hard-to-reach positions

For these applications, DIN 340 long series drills or DIN 1869 extra long drills are better options.

This point is important for B2B buyers. If your sales team understands where DIN 1897 should and should not be used, your company can reduce wrong orders and build stronger trust with professional customers.

How to Check DIN 1897 Drill Quality Before Bulk Order

Quality control is one of the most important parts of drill bit sourcing. A DIN 1897 drill may look simple, but small differences in hardness, grinding, flute shape, and point accuracy can change the user experience.

Before buying in bulk, you should check the following points.

Material Verification

The material should match your requested grade. HSS 4241, HSS 4341, HSS 6542, M35, and M42 are not the same. They have different hardness levels, heat resistance, and market positions.

Hardness Test

Hardness affects wear resistance and durability. If the hardness is too low, the drill wears quickly. If the heat treatment is unstable, the drill may break under pressure.

Point Angle Inspection

The point angle should be consistent. A poor point angle may cause walking, poor cutting, or uneven hole quality.

Flute Grinding Quality

The flute must be clean and smooth enough for chip removal. Poor flute grinding can cause heat build-up and reduce drilling efficiency.

Runout and Concentricity Check

Runout affects hole accuracy. For machine drilling and production work, concentricity very important.

Surface Finish Inspection

Surface finish should be even, clean, and free from serious defects. For branded products, appearance also affects customer confidence.

Batch Consistency

For importers and wholesalers, one good sample is not enough. You need stable quality across each batch. Batch consistency is what protects your repeat orders.
