Accupro 61534061 Jobber Drill Bit 30 Solid Carbide Altin

Product Description

The ACCUPRO 61534061 is a jobber-length drill bit sized at wire gauge 30 (0.1285 inches decimal) for precision drilling in metal, composites, and other hard materials. Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, it is engineered for high-performance cutting where heat resistance and edge retention are critical. The 140-degree split point minimizes walking and reduces thrust requirements. The web-thinned, tapered web construction improves chip evacuation, and the coolant-through design supports internal coolant delivery for extended tool life in production environments. This bit is appropriate for use by machinists, tool and die professionals, and precision fabricators working in high-speed or demanding drilling applications.

The 61534061 is suited for both CNC machining centers and manual drill presses where tight-tolerance hole quality is required. Its straight-cylindrical shank (4.00 mm diameter) fits standard collets and drill chucks commonly found in production and job-shop environments. The regular spiral flute geometry and 5xD flute-to-diameter ratio make it a practical choice for short, controlled drilling operations in materials including hardened steel, stainless, cast iron, and high-temp alloys where AlTiN coating performance is advantageous.

Key Features

• Solid carbide construction provides rigidity and wear resistance in hard and abrasive materials
• AlTiN coating enhances heat resistance and extends tool life in dry and semi-dry cutting conditions
• 140-degree point angle reduces entry force and minimizes drill walk on flat and curved surfaces
• Coolant-through capability supports internal coolant delivery for deep-hole and high-speed applications
• Web-thinned tapered web improves chip flow and lowers cutting torque
• Straight-cylindrical shank provides consistent clamping in collets and standard chucks

Compatibility

Designed as a high-performance jobber-length drill bit for use in CNC machining centers, drill presses, and automated drilling equipment accepting straight-cylindrical shank tooling in the applicable diameter range.

Installation Notes

Installation and use should be performed by qualified machinists or tool operators familiar with carbide tooling requirements. Ensure the spindle and chuck or collet are clean and free of runout before seating the shank, as carbide is brittle and sensitive to lateral loading. Set spindle speed and feed rate per the machine tool manufacturer and tooling guidelines for the workpiece material — do not exceed rated parameters. When using the coolant-through feature, confirm coolant pressure and flow are appropriate for the application before initiating the cut.
