Accupro 4500031 Solid Carbide Jobber Drill Wire 25

Product Description

The ACCUPRO 4500031 is a solid carbide jobber-length drill bit designed for drilling hardened materials that would quickly wear down high-speed steel tooling. Ground to a 140-degree split point with a UR-thinned web and a TiAlN coating, this drill resists heat and abrasion during high-duty-cycle operations. The wire gauge size 25 translates to a decimal diameter of 0.1495 inches. Overall length is 2.0625 inches with a flute length of 0.875 inches. The straight shank diameter is 0.1875 inches, allowing chucking in standard drill presses, CNC machining centers, and hand drills equipped with a precision chuck. Sold individually.

This drill bit is suited for production and maintenance machinists working in tool-and-die, aerospace, automotive, and general metalworking environments where base materials are hardened steels, stainless, or similarly difficult alloys. The slow-spiral, 2-flute geometry evacuates chips efficiently in short-hole applications. The 4xD flute-to-diameter ratio and DIN specification designation make this a recognized-standard replacement in metric or inch-compatible setups. It is intended for professional machine shop use, not wood or masonry applications.

Key Features

• Solid carbide construction provides rigidity and heat resistance beyond high-speed steel in hardened material drilling
• TiAlN coating extends tool life by reducing friction and oxidation at elevated cutting temperatures
• 140-degree point angle with UR web thinning reduces thrust force and improves self-centering on entry
• Slow-spiral, 2-flute design promotes chip clearance in short, blind, or interrupted cuts
• Straight cylindrical shank at 0.1875 inches fits standard precision chucks without an adapter
• DIN specification designation ensures dimensional conformity for repeatable tooling setups

Compatibility

Designed as an OEM-style replacement or direct tooling selection for CNC machining centers, drill presses, and hand drills accepting a straight shank of 0.1875 inches; suitable for use with standard coolant-fed or dry-run setups on hardened material workpieces.

Installation Notes

Installation and use of this drill bit should be performed by a qualified machinist or tooling professional. Secure the shank fully in a precision collet or keyed chuck before operation, and verify runout is within acceptable tolerance for the application. Always wear appropriate eye protection and follow OSHA machine-guarding requirements when operating drilling equipment. This tool is rated for dry-run use; coolant-through capability is not available on this model.
