Accupro 63310023 Carbide Drill Bit 3/16 Inch Altin

Product Description

The ACCUPRO 63310023 is a solid carbide jobber length drill bit designed for high-performance drilling in demanding trade and industrial applications. Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, it delivers extended tool life and heat resistance in hard materials. The 140-degree notched point reduces walking at entry and improves centering without a pilot hole. At 2.5 inches overall length with a 3/16-inch straight cylindrical shank, this bit fits standard drill chucks and CNC toolholders. The web-thinned, parallel web configuration reduces thrust load and aids chip evacuation during through-hole operations.

This drill bit is suited for use in ferrous metals, stainless steel, cast iron, and high-temperature alloys where standard high-speed steel bits fall short. The AlTiN coating makes it a strong choice in dry cutting or minimal-lubricant environments where heat buildup is a concern. It is commonly used by machinists, tool and die tradespeople, and precision sheet metal workers operating CNC drill presses, machining centers, or hand-held pneumatic drills. The 4xD flute-to-diameter ratio and 0.75-inch maximum drilling depth make it best suited for shallow to moderate hole depths in hard or abrasive workpieces.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides heat and oxidation resistance for extended tool life
• 140-degree notched point improves self-centering and reduces entry thrust
• Web-thinned parallel web lowers cutting resistance and aids chip flow
• Right-hand spiral flute with regular helix for efficient chip evacuation
• Straight cylindrical shank fits standard chucks and collet toolholders

Compatibility

Designed as a high-performance jobber length drill bit for use in standard 3/16-inch compatible drill chucks, collet systems, and CNC spindles that accept straight cylindrical shanks.

Installation Notes

Installation is performed by qualified machinists or trade professionals. Secure the shank fully into the chuck or collet before operation and verify runout is within acceptable limits. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable shop safety standards and tooling manufacturer guidelines for speeds and feeds when working with carbide tooling.
