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 HSS twist drill is intended for drilling larger diameters in a range of common materials including alloyed and mild steels, castings, non-ferrous metals and hard plastics. Available in diameters 10.5–16 mm for use with drills having 10 mm capacity chucks and 17–20 mm for use with drills having 13 mm capacity chucks.

Advantages

The roll-forged HSS construction and steam hardening provide improved strength and wear resistance for demanding drilling tasks. The blue-black surface finish reduces friction and corrosion, while the 118° tip angle and right-hand flute geometry ensure reliable centring and chip removal when drilling larger holes. The reduced shank allows use in drills with smaller-capacity chucks, increasing compatibility with standard electric drill models.

Suitable for

• Drilling large holes in alloyed and mild steel
• Working with castings and non-ferrous metals (e.g., aluminium, brass)
• Drilling hard plastics
• Use with standard electric handheld drills

How to use

Secure the appropriate size drill bit in the drill chuck matching the indicated chuck capacity (10 mm or 13 mm). Use a suitable drill speed and steady feed for the material being drilled; lower speeds are recommended for larger diameters and harder materials. Apply cutting fluid when working with steel or alloyed materials to extend tool life and improve chip evacuation. Maintain a stable workpiece and use clamps or a vice to prevent movement.

Usage recommendations

For best results, pre-centre or use a pilot hole when drilling large diameters, and keep the drill straight to avoid breakage. Replace the bit if excessive wear or chipping of the cutting edges is visible.
