Twist drill bit KWB 159140 1 pc Right hand rotation

The KWB 159140 twist drill bit is a right-hand rotation, roll-forged drill made to DIN 338 (type N) with a reduced shank and a 118° tip angle. It is steam-hardened and finished in a blue-black colour, designed for drilling larger diameters with standard electric drills. The bit is suitable for materials such as alloyed and mild steel, castings, non-ferrous metals and hard plastics. Available diameters: 10.5–16 mm for drills with 10 mm capacity chucks and 17–20 mm for drills with 13 mm capacity chucks.

Advantages

The roll-forged construction and steam hardening provide improved strength and wear resistance, while the reduced shank enables use in standard electric drills with limited chuck capacity. The 118° tip angle and right-hand cut (type N) make the bit versatile for clean, stable drilling in a variety of metals and hard plastics. The blue-black finish helps reduce corrosion and enhances durability.

Suitable for

• Drilling alloyed and mild steel
• Drilling cast components and castings
• Working with non-ferrous metals (e.g., aluminium, brass)
• Drilling hard plastics
• Use with standard electric drills that have 10 mm or 13 mm chucks (depending on diameter)

How to use

Select the drill diameter appropriate for your chuck capacity (10 mm or 13 mm) and secure the bit in the drill chuck. Use steady, moderate feed pressure and an appropriate cutting speed for the material being drilled. For metals, use cutting fluid to improve chip evacuation and reduce heat. Clamp the workpiece securely and start drilling at low speed to seat the tip, then increase speed as required for the material and diameter.

Использование

При высоких нагрузках и длительной работе соблюдайте рекомендованные режимы сверления и периодически проверяйте состояние сверла, чтобы избежать перегрева и преждевременного износа.
