Hertel 62748413 Jobber Drill Bit 15/32 Inch Hss Ticn

Product Description

The HERTEL 62748413 is a heavy-duty jobber-length drill bit designed for holemaking in metal and other demanding materials. Built from high-speed steel (HSS) with a titanium carbonitride (TiCN) coating, it offers improved wear resistance and extended tool life compared to uncoated HSS. The bit measures 15/32 inch (0.4688 inch) in diameter with a 135-degree split point for fast engagement and reduced walking on entry. Overall length is 5-3/4 inches with a 4-5/16 inch flute length. Machinists, tool-and-die tradespeople, and general metalworking shops will find this a dependable production-grade drill for everyday hole-making operations.

This jobber drill is suited for use in drill presses, lathes, CNC machining centers, and hand-held power drills where a straight-shank bit is required. The 15/32 inch size falls in the 0.4000 to 0.5000 inch diameter range, making it a common choice for clearance holes, through-holes, and pre-drill operations in steel, cast iron, aluminum, and similar materials. The right-hand cutting direction and regular spiral flute design pair well with standard drill chucks and collet holders. This bit conforms to NAS specification designation standards and carries a UNSPSC code of 23241634.

Key Features

• TiCN coating improves surface hardness and reduces friction for longer tool life in ferrous and non-ferrous materials
• 135-degree split point reduces thrust force and minimizes center-punch dependency on entry
• Web-thinned, tapered web construction improves chip evacuation and reduces cutting resistance
• Regular spiral, 2-flute design provides efficient chip clearing during through-hole drilling
• Straight cylindrical shank fits standard drill chucks without adapters
• Heavy-duty grade HSS construction rated for demanding production and maintenance drilling

Compatibility

Designed as a jobber-series straight-shank drill bit compatible with any drill press, CNC machining center, or hand-held power drill equipped with a chuck sized to accept a straight cylindrical shank in the 15/32 inch diameter range.

Installation Notes

Install into a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Use appropriate cutting fluid or coolant for the material being drilled to maintain bit temperature and edge life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
