Accupro 4500146 Carbide Jobber Drill 4.60mm 140 Deg Tialn

Product Description

The ACCUPRO 4500146 is a solid carbide jobber-length drill bit designed for high-performance drilling in demanding shop and production environments. It features a 4.60 mm diameter (0.1811 inch) with a 140-degree split point and a TiAlN coating that extends tool life in ferrous and abrasive materials. The two-flute, right-hand spiral design clears chips efficiently at elevated feed rates. With a 74 mm overall length and a 36 mm flute length, this drill is suited for machinists, tool-and-die setters, and CNC operators working to close-tolerance requirements on production runs or maintenance operations.

This drill bit fits standard machining and drilling applications in metalworking environments including milling machines, drill presses, and CNC machining centers. The straight cylindrical shank with a 6 mm shank diameter seats cleanly in conventional drill chucks and collet holders. The 5xD flute-to-diameter ratio and R-thinned web geometry reduce entry force and improve hole entry accuracy. It is appropriate for production drilling of steel, cast iron, stainless, and similar materials where a high-performance solid carbide tool is specified.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive workpiece materials
• TiAlN coating improves heat resistance and extends tool life at higher cutting speeds
• 140-degree point angle reduces thrust force and promotes self-centering on entry
• R-thinned web geometry lowers cutting resistance and improves chip evacuation
• Coolant-through design supports internal coolant delivery for deep-hole or high-speed applications
• DIN specification designation ensures dimensional conformance to recognized tooling standards

Compatibility

Designed as a high-performance solid carbide jobber drill for use in standard drill chucks and collet systems accepting a 6 mm straight cylindrical shank across a range of metalworking machine platforms.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Secure the shank fully within the chuck or collet and verify runout before beginning a cut. Confirm that the machine spindle speed and feed rate are appropriate for the workpiece material and drill diameter before engaging the cut. When using the coolant-through feature, ensure the coolant supply line is connected and pressurized before the tool enters the workpiece.
