Frequently Asked Questions
Everything you need to know about our products, customization options, and ordering process.
What is a stub drill bit used for?
Stub drill bits are used for accurate drilling in thin materials or confined spaces. Their shorter length provides better stability, making them ideal for CNC machining and Lathes.
What are Stubby drill bits called?
In professional engineering and B2B procurement, "Stubby" drill bits are formally known as Stub Series Drills or DIN1897 drill bits.
What is the difference between jobber and stubby?
Jobber vs. Stub Drills: Stability vs. Reach • Stability: Stubby drills are significantly stiffer, minimizing "bit walking" and vibration. This high rigidity often eliminates the need for center drilling, ensuring superior hole accuracy. • Reach: Jobber drills are the go-to for general-purpose depth (8–12x diameter), while stubby drills are optimized for shallow, high-precision holes (2.5–4x diameter). • B2B Value: For shallow drilling applications, switching to stubby drills can reduce tool breakage costs by up to 30% due to their enhanced structural strength.
How long is a Stubby drill bit?
The length of a stubby drill bit is standardized according to industrial specifications (such as DIN 1897). Generally, a stub drill is approximately 25% to 50% shorter than a jobber drill of the same diameter.
What is the difference between a jobber drill and a stub drill?
A jobber drill is a standard-length drill bit designed for general-purpose drilling. A stub drill is shorter and more rigid, making it better suited forfor high-speed, automated industrial applications
