## Long description

Spiral cutting drill bit KWB 511890 — set of three extra-long wood drills for beams with lengths of 250 mm, supplied in blister packaging.

The drills are chamfer ground and chemically blackened for industrial-quality performance and durability.

CrV steel construction and precise single-spiral shaping provide wear resistance and stable drilling. Centre point and two cutting wings reduce splintering and deliver clean hole edges. Blister packaging keeps the bits organized and easy to access.

Material: CrV steel

How to use
Mark the drilling position on the beam and secure the workpiece to prevent movement. Choose the required diameter (6, 8 or 10 mm) and install the bit in a compatible drill or drill press. Start drilling at low speed to engage the centre point, then increase speed as needed while applying steady pressure. Withdraw the bit periodically to clear chips when drilling deep holes. After use, clean the bits and store them in the blister pack to protect the cutting edges.
Рекомендации по применению
For clean, breakout‑free holes in beams, keep drill speed moderate and allow the centre point and cutting wings to do the work; avoid excessive lateral force. Use appropriate personal protective equipment and clamp timber securely before drilling.
