Accupro 4500269 Jobber Drill 10.40mm Solid Carbide Tialn

Product Description

The ACCUPRO 4500269 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding materials, particularly stainless steel. It features a 140-degree split point with proprietary geometry and an R-thinned web for reduced thrust and improved chip evacuation at entry. The TiAlN coating provides thermal resistance, extending tool life at elevated cutting speeds. With a 10.40 mm diameter and an overall length of 118.00 mm, this drill is built for precision work in CNC machining centers and rigid setups where tool runout and deflection must be minimized.

This drill is suited for metalworking applications where stainless steel, hardened alloys, or similarly abrasive materials are common workpiece materials. Its 5xD flute-to-diameter ratio and regular spiral flute design support chip clearing in deeper holes. The straight cylindrical shank accommodates standard drill chucks and collet holders. Coolant-through capability makes it compatible with high-pressure internal coolant systems, helping control heat in interrupted cuts or deep-hole operations. It is a right-hand cutting tool intended for use in machine tool spindles, not hand drilling.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating provides high-temperature resistance and extended tool life
• 140-degree proprietary point geometry reduces thrust and improves centering accuracy
• R-thinned web lowers cutting resistance at entry
• Coolant-through design supports internal high-pressure coolant delivery
• 5xD flute ratio handles chip evacuation in moderate-depth holes

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill for CNC machining applications requiring a 10.40 mm solid carbide drill with a straight cylindrical shank and coolant-through capability.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle and toolholder are clean and within specified runout tolerances before seating the shank. Verify coolant-through connections are properly sealed if internal coolant is used. Do not use this drill in handheld or underpowered setups, as solid carbide tooling is brittle and susceptible to breakage under side-loading or chatter conditions.
