Accupro 20387 Solid Carbide Jobber Drill Bit 17/64 Inch

Product Description

The ACCUPRO 20387 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding materials. It measures 17/64 inch (0.2700 inch decimal) in diameter with a 3-inch overall length and a 1.5-inch spiral flute length. The 150-degree drill point angle suits harder workpiece materials, while the titanium nitride (TiN) coating reduces friction and extends cutting life. Three right-hand spiral flutes promote efficient chip evacuation during drilling. This bit is built to ANSI specification standards and is suited for use in CNC machining centers, drill presses, and handheld power tools where consistent hole geometry is required.

This bit is appropriate for metalworking, fabrication, and general machining applications where solid carbide tooling is specified over high-speed steel. The 5xD flute-to-diameter ratio and regular spiral type make it a practical choice for through-hole and blind-hole work in steel, cast iron, hardened alloys, and similar materials. It is sold individually and fits standard straight-cylindrical shank toolholders and drill chucks sized for the 0.2500 to 0.3000 inch diameter range. Machinists, tool-and-die workers, and maintenance technicians are the primary users.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiN coating reduces cutting friction and improves tool life
• 150-degree drill point angle suited to harder workpiece materials
• Three right-hand spiral flutes for efficient chip removal
• 1.5-inch flute length on a 3-inch overall length jobber-style body
• Straight-cylindrical shank fits standard drill chucks and toolholders

Compatibility

Designed as a direct-fit replacement or standard tooling option for straight-cylindrical shank toolholders and drill chucks accepting bits in the 0.2500 to 0.3000 inch diameter range, per ANSI specification.

Installation Notes

Installation and use should be performed by machinists or qualified trades personnel familiar with rotating cutting tools. Secure the shank fully in the drill chuck or toolholder and verify runout before cutting. Always wear appropriate eye protection and follow machine-specific speed and feed recommendations for solid carbide tooling. Inspect the cutting edges for chipping or wear before each use, as carbide is brittle and can fracture if subjected to improper feeds or side loading.
