Accupro 4500069 Solid Carbide Jobber Drill 5.30 Mm

Product Description

The ACCUPRO 4500069 is a solid carbide jobber-length drill bit designed for precision drilling in hardened materials and other difficult-to-machine workpieces. It carries a TiAlN (titanium aluminum nitride) coating that improves heat resistance and extends tool life under high-speed cutting conditions. The 140-degree split point geometry reduces thrust and promotes accurate starting without center punching. With an overall length of 2.835 inches (72 mm) and a flute length of 1.26 inches (32 mm), this bit is suited for general-purpose jobber drilling applications where tight tolerances and tool durability are required. Machinists and toolroom professionals are the primary users.

This drill bit is engineered for use in hardened materials where standard high-speed steel bits would fail or wear prematurely. The slow spiral flute design improves chip evacuation in materials that produce tight, stringy chips. The straight cylindrical shank accommodates standard drill chucks and collet systems with a 6 mm shank diameter. It conforms to DIN specification standards and is appropriate for CNC machining centers, drill presses, and manual milling setups requiring consistent hole quality.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hardened workpiece materials
• TiAlN coating increases surface hardness and thermal resistance at the cutting edge
• 140-degree proprietary point geometry with UR web thinning reduces entry thrust and improves centering
• Slow spiral flute promotes controlled chip flow in hard-to-machine and abrasive materials
• Straight cylindrical shank fits standard chucks and collet holders without modification
• Right-hand cutting direction compatible with conventional clockwise spindle rotation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide jobber drill for CNC and manual drilling applications in the 5.00 mm to 6.00 mm drill bit size range per DIN specification standards.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight shank fully in a compatible chuck or collet to the manufacturer-specified grip depth before operation. Inspect the cutting edges for chipping or wear before each use, as solid carbide is brittle and susceptible to damage from improper handling. Do not exceed the spindle speed and feed rate parameters established for the workpiece material and machine setup.
