Accupro 61534004 Carbide Jobber Drill Bit 2mm Altin

Product Description

The ACCUPRO 61534004 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. Ground to a 140-degree split point with web thinning, it starts on contact without center-punching and reduces thrust in hard alloys and stainless. The AlTiN (aluminum titanium nitride) coating adds heat resistance and lubricity, extending tool life in dry or minimal-lubrication applications. At 2 mm in diameter with a 3 mm straight-cylindrical shank, this bit fits standard collet chucks and drill chucks used on CNC machining centers and manual drill presses. Coolant-through capability supports through-spindle coolant delivery for chip evacuation in deep holes.

This bit is suited for production drilling in ferrous metals, hardened steels, cast iron, titanium alloys, and composites where tool longevity and hole accuracy matter. The 5xD flute-to-diameter ratio provides adequate chip clearance for holes up to approximately five times the bit diameter. Machinists, toolmakers, and metalworking shops running tight-tolerance work will find the ISO-spec geometry consistent with standard toolpath programming. It ships individually and is appropriate for both job-shop and high-volume production environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating improves heat resistance and reduces built-up edge in ferrous machining
• 140-degree point angle with web thinning for self-centering and reduced thrust
• Coolant-through design supports through-spindle coolant for deep-hole chip evacuation
• Regular spiral flute with tapered web for balanced chip flow and bit strength
• Straight-cylindrical shank fits standard ER collets and drill chucks without adapters

Compatibility

Designed as an OEM-style solid carbide jobber drill bit for use in CNC machining centers, drill presses, and milling machines equipped with collet or chuck toolholding accepting a 3 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom professionals familiar with cutting tool setup. Ensure the machine spindle is fully stopped and locked out before loading or removing the bit from the toolholder. Verify collet or chuck bore matches the 3 mm shank diameter and that runout is within acceptable tolerance before cutting. When using coolant-through capability, confirm spindle coolant pressure and flow rate are compatible with the machine tool specifications.
