Accupro 4500362 Screw Machine Drill Bit 19/32 Inch Carbide

Product Description

The ACCUPRO 4500362 is a screw machine length drill bit designed for high-performance drilling in demanding industrial and trade applications. Built from solid carbide and coated with TiAlN (Titanium Aluminum Nitride), it delivers extended tool life when cutting through tough materials such as stainless steel. The bit measures 19/32 inch (0.5938 inches) in diameter with a 5.7090-inch overall length and a 140-degree web-thinned point angle that reduces thrust and improves centering on entry. A straight cylindrical shank at 0.6250 inches and a regular spiral right-hand flute geometry make this bit compatible with standard drill chucks and CNC setups. Coolant-through capability supports high-speed machining operations where heat management is critical.

This drill bit is suited for machining environments where stainless steel, high-alloy steels, and other hard workpiece materials are regularly encountered. The screw machine length format — shorter than a jobber-length bit — provides added rigidity and reduced deflection, making it a practical choice for production drilling, CNC machining centers, and manual mill or drill press work. It is sold individually and is appropriate for use by machinists, tool-and-die professionals, and maintenance technicians working in fabrication or industrial maintenance settings.

Key Features

• Solid carbide construction provides superior hardness and wear resistance compared to high-speed steel
• TiAlN coating extends tool life and supports higher cutting speeds in stainless steel and hard alloys
• 140-degree web-thinned (R-Thinned) point reduces entry thrust and improves hole location accuracy
• Coolant-through design allows internal coolant delivery for heat control during high-speed drilling
• Screw machine length body increases rigidity and minimizes deflection versus jobber-length bits
• Right-hand, regular spiral flute geometry promotes consistent chip evacuation

Compatibility

Designed for use with standard straight-shank drill chucks and CNC tool holders accepting a 0.6250-inch shank diameter. Primary workpiece material compatibility is stainless steels per manufacturer specification. Part of the ACCUPRO ASSC140-TA-CL series.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with carbide tooling requirements. Solid carbide bits are brittle and must be secured firmly in the chuck or collet to prevent runout-induced breakage. Ensure the machine spindle is fully stopped before installing or removing the bit. When coolant-through capability is used, verify that the machine tool coolant system pressure and flow rate are appropriate for the bit diameter before running at full cutting parameters.
