Twist drill bit KWB 209635, right-hand rotation, 1 pc

KWB 209635 is a single right-hand twist drill bit designed for standard drilling tasks in rotary drills. The bit is a roll-forged DIN 338 type N with a 118° tip angle, steam-hardened and finished in a blue-black colour. It is suitable for drilling in alloyed and mild steels, castings, non-ferrous metals and hard plastics.

Advantages

The roll-forged construction increases toughness and durability while the steam-hardening process provides improved wear resistance. The 118° tip angle offers a balance between cutting efficiency and hole quality for general-purpose drilling. A blue-black finish helps reduce corrosion and provides a consistent surface treatment.

Suitable for

• Drilling holes in alloyed and mild steel
• Working with cast iron and castings
• Drilling non-ferrous metals such as aluminium and copper
• Creating holes in hard plastic materials

Key specifications

• Standard: DIN 338, type N (straight shank, general-purpose)
• Cut direction: right-hand rotation
• Manufacturing: roll forged
• Heat treatment: steam hardened
• Tip angle: 118°
• Finish: blue-black
• Pack quantity: 1 piece

How to use

Secure the bit in the drill chuck ensuring proper centring and firm clamping. Select an appropriate rotational speed and cutting feed for the material: higher speeds for non-ferrous metals and plastics, lower speeds for alloyed and mild steels and castings. Use cutting lubricant when drilling steels and castings to extend tool life and improve hole finish. Clear chips regularly to avoid clogging and overheating.

Usage recommendations

For best results, match drill speed and pressure to the workpiece material and apply cutting fluid when machining steels or castings. Replace the bit if wear or chipping is visible to maintain hole accuracy and safety.
