Twist drill bit KWB 209685 1 pc Right hand rotation

Twist drill bit KWB 209685 for right-hand rotation, designed as a single-piece, roll-forged tool with a 118° tip angle. The bit is steam-hardened and finished in blue-black, suitable for drilling alloyed and mild steel, castings, non‑ferrous metals and hard plastics. The DIN 338, type N geometry provides a straight flute and general-purpose point for accurate, reliable hole-making in common workshop materials.

Advantages

The roll-forged construction increases core strength and resists breakage during normal drilling operations. Steam hardening gives a durable cutting edge and good wear resistance while the blue-black finish reduces corrosion. The 118° tip angle and DIN 338 type N design offer good centring and chip evacuation for a wide range of materials. Supplied as a single bit for straightforward replacement or use in job-specific tool kits.

Suitable for

• Drilling alloyed steel
• Drilling mild (carbon) steel
• Drilling cast iron and castings
• Drilling non‑ferrous metals (e.g., aluminium, brass)
• Drilling hard plastics

• Rotation: right-hand
• Tip angle: 118°
• Manufacturing method: roll-forged
• Heat treatment: steam hardened
• Surface finish: blue-black

How to use

Select proper spindle speed and feed for the material being drilled, use cutting fluid for steel and harder alloys to extend tool life, and secure the workpiece to prevent movement. Align the drill with the intended hole location and apply steady axial pressure; withdraw periodically to clear chips when drilling deeper holes. Match chuck size to the bit shank and ensure the drill is mounted concentrically before starting the machine.

Usage recommendations

For best results on steel and castings use moderate speeds with cutting lubricant; on non‑ferrous metals and plastics use higher speeds and minimal feed to avoid melting or burring.
