BOSCH 20 X 450mm 4-Cutter SDS-Plus TCT Dust Extraction Hammer Drill Bit – SPEEDCLEAN

BOSCH® SPEEDCLEAN™ Dust Extraction Hammer Drill Bits provide users with a concrete drilling solution which considerably reduces dust when used with a suitable Dust Extractor. During application, the built-in vacuum attachment pulls dust though extraction holes in the drill bit, allowing optimum material removal without additional steps. This technology results in a clean, dust-free working environment. The bit is intended for use on concrete and other masonry surfaces.

SPEEDCLEAN™ SDS-Plus Bits utilise a 4-cutter geometry (2-Cutter for 6-10 mm Bits) for longer life and also feature an accurate centring tip. SPEEDCLEAN™ Bits are available in both SDS-Plus and SDS-Max shanks compatible with most rotary hammers and is recommended for use in combination with industrial M-Class vacuum cleaners.

As proof of quality, SPEEDCLEAN™ Bits bear the test mark of the PGM® Masonry Drill Bit Association Board, guaranteeing compliance with tight tolerances, exact drilling and the firm hold of fixings. To achieve accurate results, the visibility of the wear mark indicates if the diameter of the hole is still in tolerance for metal anchor setting.
