Hertel 66694050 Jobber Drill No 6 Hss Tin 135 Deg

Product Description

The HERTEL 66694050 is a No. 6 wire-size jobber-length drill bit designed for general-purpose holemaking in metal, wood, and composite materials. Built from high speed steel with a titanium nitride (TiN) coating, it delivers extended wear resistance and reduced friction compared to uncoated HSS tooling. The split point geometry at 135 degrees reduces walking on entry and requires less thrust to initiate the cut. At 3.75 inches overall length with a 2.5-inch flute length and a 0.2040-inch straight-cylindrical shank, this bit fits standard drill chucks and is sized for consistent, repeatable hole diameters in the No. 6 wire size class. The web-thinned, tapered web construction reduces cutting resistance across the full depth of cut.

This jobber drill is suited for use in portable drills, drill presses, and CNC drilling operations requiring the No. 6 wire gauge diameter. Heavy-duty grade designation makes it appropriate for production environments and repetitive drilling cycles in ferrous and non-ferrous metals. It is a right-hand cutting tool with a regular spiral and two flutes, consistent with standard jobber-series configurations used by machinists, maintenance technicians, and general fabrication trades.

Key Features

• 135-degree split point reduces walking on entry and lowers required thrust
• TiN coating extends tool life and reduces friction during cutting
• High speed steel construction suitable for ferrous and non-ferrous materials
• Web-thinned tapered web reduces cutting resistance at full depth
• 0.2040-inch straight-cylindrical shank fits standard drill chucks without modification
• Heavy-duty grade rated for production and repetitive drilling cycles

Compatibility

Designed as a standard jobber-series drill bit for use in any drill press, hand drill, or CNC drilling setup accepting a 0.2040-inch straight-cylindrical shank. Conforms to NAS specification designation for jobber-length tooling.

Installation Notes

This bit is installed and removed by a licensed machinist or qualified technician using a standard drill chuck or collet system rated for the shank diameter. Ensure the drill spindle is fully stopped and power is isolated before changing tooling. Secure the workpiece firmly before drilling to prevent movement and maintain hole accuracy. Do not exceed the recommended feed rate or spindle speed for the material being drilled, as overloading an HSS bit can cause premature wear or breakage.
