Punta a spirale KWB 042912 1,2 cm

Japan auger bit KWB 042912 with 1.2 cm diameter, single-piece construction and hexagon 1/4" shaft is designed for precise drilling in all types of wood. The tool features a super-sharp thin polished tip section and a main blade in CV steel, finished in black shiny polish, to minimise fraying and produce small shavings that are quickly evacuated. It is suitable for use with cordless and tethered machines and is intended for drilling into wooden beams and visible wooden surfaces where clean holes are required.

Advantages

The specially ground thin tip section and main blade ensure fray-proof drilling into both hard and soft wood. Small, easily removed shavings reduce clogging and allow continuous work. The hexagon 1/4" shaft (ISO 1173, E 6.3) provides secure engagement with drill chucks and quick-change holders for precise, effortless drilling. Hardened CV steel construction and polished finish improve durability and cutting performance.

How to use

Mark the drilling position on the workpiece and secure the wooden part to prevent movement. Install the auger bit into the drill chuck or quick-change holder, ensuring the hexagon shaft is fully engaged. Start drilling at low speed to guide the thin tip into the material, then increase speed as needed while maintaining steady pressure. Periodically withdraw the bit to clear chips if drilling deep holes, then resume until the required depth is reached.

Recommendations

For best results use with proper clamping and appropriate drill speed for the wood type. Inspect the bit before use and sharpen or replace if cutting performance deteriorates. When drilling visible surfaces, test on a scrap piece to confirm hole appearance.
