Accupro 4500463 Taper Length Drill Bit 13/64 Solid Carbide

Product Description

The ACCUPRO 4500463 is a taper length drill bit engineered for high-performance drilling in demanding materials. Built from solid carbide and coated with TiAlN, it holds up under the heat and abrasion generated when cutting stainless steel and other hard alloys. The 140-degree split point reduces walking at entry and lowers the thrust needed to start the cut. With a flute length of approximately 2.24 inches and an overall length of approximately 3.74 inches, this bit fits standard drill chucks and CNC setups running straight-shank tooling. Coolant-through capability makes it well suited for automated machining environments where chip evacuation and heat management are critical.

This drill bit is designed for metalworking applications where tool life and hole quality in tough materials are priorities. Its R-thinned web reduces cutting resistance, making it a practical choice for production drilling in stainless steel, hardened alloys, and similar ferrous materials. The spiral flute geometry promotes consistent chip removal in both manual and CNC-controlled operations. Machinists and toolroom technicians working in manufacturing, fabrication, and precision machining shops are the primary installers and users of this bit.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating extends tool life under high-heat cutting conditions
• 140-degree point angle reduces entry walking and thrust requirements
• Coolant-through design supports chip evacuation in automated setups
• R-thinned web lowers cutting resistance at the drill center
• Straight cylindrical shank fits standard chucks and collets

Compatibility

Designed as an OEM-style replacement or direct-use taper length drill bit for applications requiring a 13/64 inch straight-shank carbide bit with a 140-degree point and coolant-through capability.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with carbide tooling. Secure the straight shank firmly in a compatible chuck or collet before operation and verify that runout is within acceptable limits for the application. When using the coolant-through feature, confirm that the machine spindle and toolholder are set up to deliver coolant at adequate pressure. Do not use carbide drills in hand-held drilling operations, as carbide is brittle and susceptible to breakage from lateral loading.
