Accupro 10347 Jobber Drill Bit 1/8 in Solid Carbide 3 Flute

Product Description

The ACCUPRO 10347 is a solid carbide jobber length drill bit designed for precision drilling in demanding applications. Built from solid carbide with a bright uncoated finish, it delivers the rigidity and wear resistance needed for hard materials and tight-tolerance work. The 1/8 inch (0.1250 inch) diameter bit features a 150-degree drill point angle and a 3-flute spiral configuration with a regular spiral type, giving it strong chip evacuation and a clean entry point. Overall length is 2.25 inches with a 0.75 inch flute length. Machinists, tool-and-die tradespeople, and industrial maintenance techs are the typical end users.

This bit suits CNC machining centers, drill presses, and manual operations where a small-diameter, short-flute carbide tool is required. The straight cylindrical shank fits standard collets and chucks without modification. Right-hand cutting direction makes it compatible with conventional drilling setups. It is sized within the 0.1000 to 0.1500 inch decimal inch range, making it a go-to choice for fine-bore work in metals, composites, and similar materials where high-speed steel tooling falls short. Packaged as a single unit per the ANSI specification designation.

Key Features

• Solid carbide construction for superior hardness and wear resistance versus HSS alternatives
• 150-degree drill point angle for reduced thrust and cleaner entry in harder workpiece materials
• 3-flute spiral design improves chip clearance and surface finish in the bore
• Bright uncoated finish suitable for a wide range of base materials without coating interaction concerns
• Straight cylindrical shank fits standard collets and chucks with no adapter required
• ANSI specification compliance ensures dimensional consistency for production environments

Compatibility

Designed as a jobber length solid carbide drill bit with a straight cylindrical shank, compatible with standard collets, chucks, and drill presses that accept 1/8 inch shank tooling in conventional right-hand drilling setups.

Installation Notes

Installation and use of carbide drill bits should be performed by qualified machinists or tooling technicians familiar with proper speeds, feeds, and workholding practices. Secure the workpiece and verify spindle runout is within acceptable limits before operation, as carbide is brittle and susceptible to chipping under lateral loading or vibration. Do not use this bit for hammer drilling or in applications that generate side loads. Follow machine manufacturer guidelines for collet torque and tool protrusion length.
