Application Notes
Discover the versatile applications and material compatibility of our products

Drilling Aluminum Alloy
- •These burr-free sheet metal drill bits feature sharp precision cutting edges. They penetrate aluminum alloy effortlessly with low friction and fast chip removal. No rough edges or material deformation, delivering clean, smooth round holes for thin alloy sheet processing.

Drilling Stainless Steel
- •Built for stainless steel sheet drilling, the bits own high hardness and heat resistance. Special cutting geometry reduces torque and avoids overheating. It drills steadily without burrs, keeping holes neat and round for heavy-duty sheet metal work.

Drilling Wood
- •Perfect for wood drilling, these bits cut cleanly without splintering. Optimized flute design discharges wood chips quickly and prevents clogging. It achieves burr-free smooth holes, suitable for wooden panels and general woodworking applications.
