Makita HSS-Co Metal Drill Bit 2.5 x 57 mm

The Makita D-17304 Metal Drill Bit 2.5 × 57 mm HSS-Co is a single-piece drilling tool engineered for hard metal applications. It is made from M35 high-speed steel, giving it a sturdy construction suited to demanding workshop repairs and routine maintenance. Target materials include standard steel, stainless steel, and hardened metal alloys. Users carrying out fabrication work will find it well suited to cutting through dense metallic components. Designed to work with standard hand power tools, the bit focuses on consistent material removal.

A 118-degree point angle shapes the cutting tip, allowing holes to be started reliably. This geometry reduces the tendency for the bit to wander when beginning a cut on a smooth surface. Heat resistance is a primary advantage of the cobalt-alloy cutting edge, helping the bit last longer during sustained use compared with standard high-speed steel alternatives. The bit is intended for use with a standard electric drill, which serves as the power source for all rated tasks. Steady application lets the user penetrate solid metal plates while keeping direct control over the cutting process.

• 2.5 mm bit diameter provides precise sizing for small-scale metalwork and component fabrication.
• 57 mm overall length gives sufficient reach for typical workshop drilling.
• 30 mm usable working length sets the maximum depth for penetrating solid materials.
• Cylindrical shank fits securely into standard drill chucks without the need for special adapters.
• 5% cobalt content in the cutting edge increases durability beyond standard steel compositions.
