Accupro 4500158 Jobber Drill 3.40mm Carbide Tialn

Product Description

The ACCUPRO 4500158 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. Built to DIN specification, it features a 140-degree split point with R-thinned web geometry that reduces thrust and improves centering on entry. The TiAlN coating adds heat resistance and extends tool life in high-speed applications. At 3.40 mm (0.1339 inches) in diameter with a 66.00 mm (2.5984 inches) overall length and a 28.00 mm (1.1024 inches) flute length, this drill is sized for precision work in production and maintenance environments. Coolant-through capability supports chip evacuation and thermal control during deep-hole operations.

This drill bit is engineered for cutting stainless steel and similarly tough ferrous and non-ferrous alloys where heat buildup and work hardening are primary concerns. The right-hand cutting direction, two-flute regular spiral configuration, and 5xD flute-to-diameter ratio make it well-suited for CNC machining centers, drill presses, and hand-held operations requiring consistent hole quality. The 6 mm straight cylindrical shank seats securely in standard collets and drill chucks. Machinists, toolmakers, and maintenance technicians working in aerospace, fabrication, and industrial manufacturing will find this drill appropriate for tight-tolerance hole applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating provides elevated heat resistance and extends cutting life
• 140-degree point angle with R-thinned web reduces walking and entry thrust
• Coolant-through design supports chip clearing in deep or interrupted cuts
• Right-hand, two-flute regular spiral optimized for stainless steel and ferrous alloys
• DIN specification geometry for consistent, repeatable performance

Compatibility

Designed as a high-performance replacement or production drill for applications requiring a 3.40 mm diameter hole in stainless steel and comparable hard materials. Compatible with standard 6 mm straight-shank collets and drill chucks.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom technicians familiar with CNC or manual drilling equipment. Secure the straight shank fully in the collet or chuck before operation and verify runout is within acceptable limits for the application. Activate coolant-through supply before initiating the cut when drilling stainless steel to manage heat and chip evacuation. Do not exceed the spindle speed and feed rate parameters established for solid carbide tooling in the specific workpiece material.
