Reduced shank rolled HSS twist drill bits

• Manufacturing art:rolled
• Point Angle: 118 Degree, 135 Split Point
• Shank: reduced Shank
• Size(mm): 10.5mm-40.0mm
• Surface Finish:black oxide coating Finish
• Technical Data

• Diameter: 3–16mm; reduced shank (e.g., 10mm shank for 12–16mm bits); total length 80–150mm.
• Material & Process: HSS M2; rolled flutes; 118° point angle; right-hand spiral; H8 tolerance.
• Others: Black oxide coating; straight reduced shank (fits standard chucks); compliant with DIN 338.

Advantages

• Reduced shank fits small chucks, enabling large-diameter drilling without special tools.
• Black oxide coating resists rust, reduces friction, and improves chip flow.
• Rolled process ensures cost-effectiveness; HSS M2 offers reliable durability for general materials.
• Versatile for steel, aluminum, plastic; ideal for DIY and light industrial use with standard drills.
