ENT 09256 6 Piece Wood Drill Bit Set HSS G Diameter 4 12 mm Usable Length 100 Total 150

This wood drill bit set contains 6 wood drill bits in long design and diameters 4, 5, 6, 8, 10 and 12 mm. The 100 mm usable length and 150 mm total length offer more leeway, making these drill bits especially suitable for deep drill holes, blind holes and through-holes. Centring tip and taper - All wood drill bits have a centring tip and two taper taps. The centring tip guarantees precise drilling without "running" of the drill. The taper cutters allow precise and circular drilling and a clean hole edge quality. Spiral - The precision-ground spiral with its smooth surface ensures optimal concentricity when drilling and clean chip ejection. Steel quality: the hardened HS steel according to EN ISO 4957 with a hardness of at least 62 HRC has a high wear resistance and high heat resistance. Concentricity – The ground production results in improved concentricity compared to flat-rolled wood drills, as no bending occurs during production Transition from spiral to shaft - The smooth and continuous transition from the spiral to the shaft contributes to good chip ejection. Shaft marking: the punched dimension marking ensures good readability of all features even after repeated use of the drills.
