Accupro 4500010 Jobber Drill Bit Wire 26 Solid Carbide Tialn

Product Description

The ACCUPRO 4500010 is a solid carbide jobber-length drill bit sized to wire gauge 26 (0.1470 inches), designed for drilling hardened materials where standard high-speed steel tooling loses its edge. It runs a 140-degree split point with UR web thinning to reduce thrust and improve centering on entry. The TiAlN coating adds heat resistance, making it suited for dry or minimal-lubrication drilling in tool steels, hardened alloys, and abrasion-resistant materials. With an overall length of 2 inches and a slow spiral flute design, it maintains chip control in tough substrates. Licensed machinists and tool-room professionals are the primary installers of this bit.

This drill bit is built for precision metalworking applications involving hardened workpiece materials. The slow spiral flute geometry helps manage chip evacuation in materials that tend to work-harden during cutting. The straight cylindrical shank measures 3/16 inch (0.1875 inches) in diameter, fitting standard drill chucks and collet holders. It is appropriate for CNC machining centers, drill presses, and hand-held drilling operations where a rigid, accurate setup is maintained. The 13/16-inch flute length provides adequate cutting depth for most through-hole and blind-hole applications in this size range.

Key Features

• Solid carbide construction for rigidity and wear resistance in hardened materials
• TiAlN coating for elevated heat resistance during dry or semi-dry drilling
• 140-degree point angle with UR web thinning reduces entry thrust and improves self-centering
• Slow spiral flute design aids chip control in tough, work-hardening alloys
• Straight cylindrical shank fits standard chucks and collet systems
• DIN specification designation for consistent dimensional standards

Compatibility

Designed as an OEM-style replacement or direct tooling option for applications requiring a wire gauge 26 solid carbide drill bit with a straight shank and 140-degree point in hardened material service.

Installation Notes

Installation of this bit is performed by machinists or tool-room technicians in a controlled machine setup. Ensure the drill chuck or collet is clean and the shank is fully seated before tightening to manufacturer-specified torque for the holding device. Solid carbide is brittle compared to high-speed steel — avoid side loading, interrupted cuts without proper fixturing, or dropping the bit on hard surfaces. Confirm spindle speed and feed rate are appropriate for the workpiece hardness before beginning the cut.
