Accupro 4500461 Taper Length Drill Bit 15/64 Inch Carbide

Product Description

The ACCUPRO 4500461 is a taper length drill bit engineered for high-performance drilling in demanding materials, including stainless steel. Built from solid carbide and coated with TiAlN (Titanium Aluminum Nitride), this bit delivers exceptional heat resistance and tool life in applications where standard high-speed steel falls short. The 140-degree split point reduces walking and minimizes breakthrough burrs, making it well suited for precision work. With a flute-to-diameter ratio of 8xD and R-thinned web geometry, chip evacuation stays consistent even in deep-hole drilling scenarios. This bit is a go-to for machinists and fabricators who need reliable performance in difficult materials.

This drill bit is designed for use in CNC machining centers, drill presses, and manual mills where a straight-shank taper length tool is required. Its 57 mm flute length and 95 mm overall length make it appropriate for intermediate-depth holes in ferrous metals, including stainless steel and hardened alloys. The right-hand spiral flute and coolant-through capability suit it to production environments where tool life and finish quality are priorities. Typical installers include machinists, tool-and-die technicians, and metal fabrication professionals.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• TiAlN coating provides high heat resistance and reduces built-up edge in stainless steel
• 140-degree point angle reduces drill walk and improves hole entry accuracy
• R-thinned web reduces thrust force and improves chip flow at the cutting tip
• Coolant-through design supports internal coolant delivery for deep-hole applications
• Straight cylindrical shank with 6 mm shank diameter fits standard collet and chuck systems

Compatibility

Designed as a high-performance taper length drill bit for use in CNC machining centers and drill presses that accept straight-cylindrical shank tooling with a 6 mm shank diameter. Rated for stainless steel and other demanding ferrous material applications.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with carbide tooling. Always confirm the spindle and collet or chuck are clean and properly secured before inserting the bit, as runout can fracture solid carbide. Power down the machine and lock out energy sources before changing tooling. When using the coolant-through feature, verify coolant pressure and flow rate are within the machine's recommended range before starting the cut.
