ENT 09225 25 Piece HSS Wood Drill Bit Set 1 13 mm in 0.5mm Increments Bits

Centre point and spurs - The centre point guarantees precise drilling without the wood drill bits running out of alignment. The spurs enable precise and circular drilling and a clean hole edge quality. Spiral - The high-precision spiral of the drill bits for wood with its smooth surface ensures optimum concentricity during 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 as well as a high heat resistance. Concentricity - The machined fabrication of the drill bit sets wood results in improved concentricity compared to flat-rolled wood drills, as no bending occurs during fabrication. Shank - The drill bits wood have shanks ranging from from 1 - 10 mm. Drills from 10.5 mm diameter have a stepped 10 mm shank, so you can use any drill bit on a hand drill or cordless drill. Shank marking - The stamped measurement marking ensures good readability of the Ø even after repeated use of the wood drill bit sets.
