Overview

Provide your customers with the most comprehensive metric drilling solution available. The 25-Piece HSS Twist Drill Bit Set from Shanghai Daoge Xiaoman Tools Co., Ltd. features an unbroken sizing matrix from 1.0mm all the way up to 13.0mm (in precise 0.5mm increments). This guarantees that mechanics, fabricators, and DIYers will always have the exact diameter required for any general-purpose application. Forged from premium High-Speed Steel (HSS), these jobber-length bits deliver exceptional toughness and wear resistance when boring through mild steel, aluminum, copper, wood, and plastics. Rather than heavy metal boxes that are prone to denting and rust, this 25-piece master set is housed in an Impact-Resistant Plastic Index Case. This modern packaging reduces shipping weight for global distributors while keeping the bits secure, organized, and shielded from job-site moisture. Available for full OEM private-label manufacturing.
