Hertel 62748223 Jobber Drill 1/8 in 135 Deg Hss Ticn

Product Description

The HERTEL 62748223 is a 1/8 inch diameter jobber-length drill bit designed for general-purpose holemaking in metal, steel, and similar materials. Built from high speed steel (HSS) with a titanium carbonitride (TiCN) coating, it delivers improved surface hardness and wear resistance compared to uncoated HSS tooling. The 135-degree split point reduces walking on entry and lowers thrust requirements, making it well-suited for drilling without a center punch in many applications. Overall length is 2.75 inches with a 1.625 inch flute length. The straight cylindrical shank fits standard drill chucks. This bit is graded heavy duty and carries a NAS specification designation.

This jobber drill is appropriate for production and maintenance drilling tasks across metalworking, fabrication, and light industrial environments. The regular spiral flute geometry promotes chip evacuation in through-hole operations. With a 0.1250 inch decimal diameter and right-hand cutting direction, it fits standard drill press, handheld, and CNC drill applications where a small-diameter, high-precision entry hole is required. The web-thinned, tapered web configuration reduces cutting resistance at the chisel edge.

Key Features

• 1/8 inch (0.1250 inch) diameter, jobber-series length
• 135-degree split point for reduced walking and lower entry thrust
• TiCN coating increases surface hardness and extends tool life versus uncoated HSS
• Regular spiral flute with web-thinned tapered web for efficient chip removal
• Right-hand cutting, straight cylindrical shank for universal chuck compatibility
• Heavy duty grade with NAS specification designation

Compatibility

Designed as an OEM-style replacement or direct-use jobber drill for any standard drill press, handheld drill, or CNC spindle accepting a straight cylindrical shank in the 1/8 inch size range.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with drilling operations. Secure the straight shank fully in the chuck and verify concentricity before operation. Always power down and de-energize the drilling equipment before changing bits. Follow applicable shop safety standards and manufacturer guidelines for feed rate and speed selection based on workpiece material.
