Hertel 84579127 Jobber Drill 11/64 in Hss 135 Deg

Product Description

The HERTEL 84579127 is a high speed steel jobber-length drill bit designed for precision holemaking in metal, wood, and similar materials. It features a 135-degree split point that reduces walking on contact, allowing the bit to start on location without a center punch in most applications. An oxide coating helps reduce friction and extend tool life during repeated use. The 2-flute, right-hand spiral configuration evacuates chips efficiently, keeping the cutting zone clear. This bit is built to heavy-duty grade standards and is a dependable choice for machinists, maintenance technicians, and trade professionals who need consistent performance from a jobber-series drill.

This drill bit is suited for general-purpose holemaking tasks on the bench, at a machine tool, or in the field. The straight-cylindrical shank fits standard 3-jaw drill chucks found on drill presses, hand drills, and lathes. It is commonly used in HVAC, plumbing, electrical, and general mechanical work where precise, clean holes are required in ferrous and non-ferrous materials. The regular spiral and tapered web configuration make it effective across a range of material types encountered in everyday trade applications.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotating cutting tools.

Always wear appropriate eye protection and follow applicable shop safety procedures when operating drill equipment. Use appropriate cutting fluid for ferrous materials to reduce heat buildup and extend bit life.
