Twist drill bit kwb HSS Twist Drills 1 pc Right hand rotation

Twist drill bit kwb HSS 1 pc, right-hand rotation, conforms to DIN 338. This solid high-speed steel (HSS) drill features a type N, roll-forged body with blue-black finish and steam hardening. The tip angle is 118° and the shank is reduced to fit standard drill chucks. The drill is intended for drilling large diameters in materials such as alloyed and mild steel, castings, non-ferrous metals and hard plastics. Available diameters 10.5–16 mm for use in drills with 10 mm capacity chucks and 17–20 mm for drills with 13 mm capacity chucks.

Advantages

The kwb HSS twist drill offers precise cutting geometry (118° tip) and a type N flute for general-purpose drilling. Roll forging and steam hardening improve wear resistance and toughness, while the reduced shank allows use in standard electric drills with smaller-capacity chucks. The blue-black surface finish provides additional corrosion protection.

Suitable for

• Drilling alloyed and mild steel
• Working with cast iron and castings
• Drilling non-ferrous metals (aluminium, brass, copper)
• Drilling hard plastics

How to use

Secure the reduced shank in the drill chuck appropriate for the specified chuck capacity. Choose a suitable cutting speed and apply steady feed pressure; use cutting fluid when drilling steel or alloyed materials to extend tool life and improve hole quality. Start drilling at low speed to establish the center, then increase speed as appropriate for the material and diameter. Regularly clear chips from the flutes to prevent clogging.

Usage recommendations

For best results, match the drill diameter to the drill's chuck capacity as stated (10.5–16 mm for 10 mm chucks, 17–20 mm for 13 mm chucks), use appropriate cutting lubricant on ferrous materials, and avoid excessive feed that can cause breakage. Inspect the drill before use and replace if the cutting edges are worn or damaged.
