19-Piece M35 Cobalt Steel Metric Drill Bit Set, 1-10mm - style: 19pcs(Metal Case)

About this item

• PREMIUM M35 COBALT STEEL – Crafted from High-Speed Steel with 5% Cobalt (HSS-CO), this alloy achieves a Rockwell Hardness of up to 67. It offers superior heat resistance and wear durability, lasting up to 12X longer than standard HSS bits, making it the ultimate choice for heavy-duty drilling.
• MASTER OF HARD METALS – Specifically engineered to cut through tough, high-tensile materials. It performs exceptionally well on abrasive metals like stainless steel, cast iron, and titanium alloys, while also slicing effortlessly through softer materials like aluminum, wood, and plastic.
• PRECISION 135° SPLIT POINT – Features a self-centering 135° split point geometry that bites into the material immediately. This prevents "walking" or wandering on smooth surfaces, eliminates the need for a center punch, and reduces the pressure required to penetrate.
• FULL 19-PIECE METRIC SET – Includes a complete range of metric sizes from 1mm to 10mm in 0.5mm increments (1, 1.5, 2... up to 10mm). The straight shank design features a chamfered end on larger bits for a secure grip in standard drill chucks, preventing slippage under high torque.
• DURABLE METAL STORAGE CASE – The bits are housed in a rugged, heavy-duty metal index case. Clearly labeled size markings allow for instant identification and organization, keeping your tools secure during transport and tough working conditions.
