Accupro 63309611 Carbide Jobber Drill Bit 1.5 Mm Altin

Product Description

The ACCUPRO 63309611 is a solid carbide jobber-length drill bit designed for precision drilling in hard and abrasive materials. It measures 1.5 mm in diameter (0.0591 inches) with an overall length of 38 mm (1.496 inches) and a flute length of 11 mm (0.433 inches). The bit features an AlTiN (aluminum titanium nitride) coating that increases surface hardness and heat resistance, extending tool life in demanding applications. The 140-degree notched point reduces thrust and improves self-centering at entry. Right-hand spiral flute geometry evacuates chips efficiently during the cut.

This drill bit is suited for machining operations in metalworking, aerospace, automotive, and precision manufacturing environments. It handles hardened steels, stainless steels, cast iron, and other tough alloys where high-performance carbide tooling is required. The straight-cylindrical shank fits standard drill chucks and collet systems. A maximum drilling depth of 8.80 mm (0.346 inches) and a shank diameter of 3.00 mm (0.118 inches) make it appropriate for CNC machining centers, drill presses, and manual machines running at appropriate spindle speeds for the material.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating improves heat resistance and extends cutting tool life
• 140-degree notched point reduces entry thrust and improves hole positioning accuracy
• Right-hand regular spiral flute promotes efficient chip evacuation
• Web-thinned parallel web reduces cutting forces at the tip
• Straight-cylindrical shank compatible with standard drill chucks and collet holders

Compatibility

Designed as a high-performance replacement jobber-length drill bit for applications requiring a 1.5 mm solid carbide bit with AlTiN coating, fitting any standard chuck or collet system that accepts a 3.00 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with carbide cutting tool setup. Ensure the machine spindle is fully stopped before installing or removing the bit from the chuck or collet. Run at spindle speeds and feed rates appropriate for the workpiece material and bit diameter — carbide bits require proper speeds to avoid chipping or fracture. Do not use this bit for hand-drilling applications; it is intended for rigid machine setups only.
