Accupro 4500229 Solid Carbide Jobber Drill 14.50 Mm

Product Description

The ACCUPRO 4500229 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials. It measures 14.50 mm in diameter with an overall length of 5.2362 inches and a flute length of 3.2677 inches. The 140-degree split point geometry reduces walking and penetrates hard materials more efficiently than a standard 118-degree point. A TiAlN coating extends tool life under high-heat conditions. Coolant-through capability supports chip evacuation and thermal management during deep-hole operations. This drill is suited for machinists, tool-and-die shops, and production environments requiring consistent results in difficult materials.

This drill bit is optimized for stainless steel and other hard or abrasive workpiece materials where standard high-speed steel tooling underperforms. The right-hand cutting direction and regular spiral flute design make it compatible with standard CNC machining centers, drill presses, and manual mills. The straight cylindrical shank measures 16 mm in diameter, fitting standard ER or straight-bore collet chucks. With a 5xD flute-to-diameter ratio, it handles moderate-depth holes without excessive deflection. Typical applications include aerospace, medical, and general metalworking production runs where tight tolerances and long tool life are required.

Key Features

• 14.50 mm diameter solid carbide construction for rigidity and wear resistance
• TiAlN coating for extended tool life in high-temperature cutting applications
• 140-degree proprietary point angle reduces entry thrust and minimizes walking
• Coolant-through design supports chip evacuation in deep-hole drilling
• R-thinned web reduces chisel edge load and improves penetration rate
• Right-hand regular spiral flute for efficient chip removal in stainless steel

Compatibility

Designed for use in standard CNC machining centers and drill presses accepting a 16 mm straight cylindrical shank. Primary workpiece material designation is stainless steel, within the 12.50 mm to 15.00 mm drill bit size range per DIN specification.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle at a full stop and the machine locked out per applicable safety procedures. Ensure the collet chuck or tool holder is clean and properly torqued before running. Verify coolant-through passages are clear and flow is confirmed before beginning a drilling cycle. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid premature tool wear or fracture.
