Hex reduced shank milled HSS M2 twist drill bits

• Manufacturing art:milled
• Surface Finish:titanium coating Finish
• Size(mm): 10.5mm-40.0mm
• Point Angle: 118 Degree, 135 Split Point
• Shank: Hex reduced Shank

Technical Data

• Dimensions: Drill diameter ranges 1–13mm; hex reduced shank commonly 1/4″ (fits quick-change chucks), total length follows standard jobber length (around 50–120mm).
• Core Parameters: HSS M2 material; milled flutes; 118° or 135° split point; regular N-type right-hand spiral; H8 tolerance and compliant with DIN 338.
• Other Features: Amber coating on the surface; hex reduced shank structure for tool matching.

Advantages

• The hex reduced shank avoids slipping in chucks, enables high-torque transmission, and fits small quick-change chucks for large-diameter drilling without special tools.
• Milled processing ensures precise flute shapes and sharp cutting edges, improving drilling accuracy and chip removal efficiency.
• Amber coating enhances wear resistance, reduces friction and heat buildup, and effectively prevents rust during storage and use.
• HSS M2 delivers reliable heat resistance and durability, suitable for drilling steel, aluminum, copper, plastic and other materials, ideal for DIY, maintenance and light industrial scenarios.
