Bosch puupora vakiomallinen keskikärjellä 3 mm halkaisija 61 mm pituus

Bosch Standard brad point drill bit, 3 mm diameter and 61 mm overall length, is designed for precise wood drilling. The brad point and shoulder cutter ensure accurate centring and clean hole edges with reduced splintering. The drill bit has two flutes and a black ground point finish suitable for use in both hard and soft wood.

Advantages

The centring tip provides accurate starts and prevents wandering, while the shoulder cutter produces clean, well-defined hole edges. Two flutes allow efficient chip removal during drilling. The ground black point improves durability and cutting performance for wood-working tasks.

How to use

Mark the drilling position and secure the workpiece to prevent movement. Use a suitable drill or drill press, align the brad point with the mark, and apply steady pressure to allow the centring tip to start the hole. Drill at appropriate speed for the wood species and withdraw occasionally to clear chips if necessary. For through-holes, support the exit side to minimise tear-out.

Recommendations

Use appropriate drill speeds for the wood type and clamp the workpiece securely. For best results, start with a pilot or centre mark and clear chips regularly; store the bit in its blister package or a bit holder to protect the ground point.
