Hertel C.40W.1032 Taper Length Drill 0.4062 in Hss

Product Description

The HERTEL C.40W.1032 is a taper length twist drill bit designed for precision drilling in metal and general industrial applications. It measures 0.4062 inches (13/32 inch) in diameter with a 118-degree standard point angle and a black oxide finish that reduces friction and provides moderate corrosion resistance. The overall length is 7 inches with a flute length of 4.375 inches, giving it extended reach beyond a jobber-length bit. The high-speed steel (HSS) construction handles a wide range of workpiece materials. This bit is installed and used by machinists, millwrights, and maintenance technicians working on production or repair drilling tasks.

This taper length drill bit suits applications where additional reach is needed beyond a standard jobber drill, such as drilling through thicker stock or reaching into recessed areas. The right-hand spiral flute with a web-thinned, tapered web configuration improves chip evacuation and reduces the thrust force needed to start and maintain the cut. The straight-cylindrical shank fits standard drill chucks on drill presses, CNC drilling machines, and hand-held power drills. It is well suited for metalworking shops, maintenance facilities, and general fabrication environments.

Key Features

• 13/32 inch (0.4062 inches) diameter with matching straight-cylindrical shank for secure chuck grip
• 118-degree standard point angle for general-purpose drilling across common metals and plastics
• Black oxide finish reduces friction and provides light corrosion resistance during storage and use
• Web-thinned, tapered web reduces cutting thrust and improves hole entry performance
• Right-hand regular spiral flute promotes consistent chip evacuation in through-hole and blind-hole drilling
• 7-inch overall length provides extended reach compared to standard jobber-length drills

Compatibility

Designed as an OEM-style taper length drill bit suitable for use in standard drill chucks, drill presses, and CNC drilling equipment accepting straight-cylindrical shank bits in the 13/32 inch diameter range.

Installation Notes

Install this bit in a properly sized drill chuck and verify the shank is fully seated and securely tightened before operation. Always power down and lock out the machine before changing bits. Use appropriate cutting fluid for the workpiece material to extend tool life and improve hole quality. Follow applicable workplace safety standards and machine manufacturer guidelines when operating drilling equipment.
