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

Twist drill bit KWB HSS, right-hand rotation, roll-forged and steam-hardened with blue-black finish. Conforming to DIN 338 type N with a 118° tip angle and reduced shank, this drill bit is intended for drilling larger diameters in standard electric drills and is suitable for alloyed and mild steels, 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 use in drills with 13 mm capacity chucks.

Advantages

Roll-forged HSS construction combined with steam hardening provides improved strength and wear resistance. The blue-black surface finish reduces friction and corrosion. The DIN 338 type N geometry with a 118° tip angle ensures accurate centring and controlled chip formation. Reduced shank sizes allow use in drills with smaller-capacity chucks, expanding compatibility with common electric drills.

Suitable for

• Drilling alloyed and mild steels
• Drilling cast iron and castings
• Drilling non-ferrous metals (aluminium, copper, brass)
• Drilling hard plastics
• Use in standard electric drills with matching chuck capacities (10 mm or 13 mm)

How to use

Select a drill with a chuck capacity that matches the reduced shank diameter (10 mm capacity for 10.5–16 mm sizes, 13 mm capacity for 17–20 mm sizes). Secure the bit in the chuck, set the drill to the correct speed for the material being drilled, and apply steady, moderate pressure. Use cutting fluid when drilling steels and harder alloys to extend tool life and improve chip evacuation. Clear chips regularly to avoid clogging and overheating.

Usage recommendations

For best results, pre-centre or use a pilot hole when drilling large diameters, maintain appropriate cutting speeds and cooling for the material, and replace the bit if wear degrades hole quality. Do not exceed the recommended chuck capacity for the reduced shank sizes.
