Hertel 18723 Countersink 3/16 in 60 Degree 4 Flute Hss

Product Description

The HERTEL 18723 is a single-piece countersink designed for creating clean, chamfered entry points in metal, wood, and composite materials. Built from high speed steel, this tool delivers consistent cutting performance and edge retention through repeated use. The 60-degree included angle suits the most common fastener head geometries used in machining and fabrication. With four flutes, it produces a smooth, chatter-resistant finish across a range of workpiece materials. The straight cylindrical shank measures 3/16 inch, matching the 3/16 inch head diameter for a compact, balanced profile suited to smaller-diameter fastener prep work.

This countersink is well suited for bench machining, drill press operations, and hand-held power drill applications where precision chamfering is required. It fits standard 3/16 inch collets and chucks, making it a practical addition to a machinist or fabricator toolkit. Typical applications include deburring drilled holes and seating flat-head and oval-head machine screws flush with workpiece surfaces in light manufacturing, maintenance, and repair environments.

Installation Notes

Installation is performed by machinists or skilled tradespeople using a drill press, milling machine, or handheld power drill with an appropriate collet or chuck. Secure the straight shank firmly before operation to prevent slippage. Always deburr the drilled pilot hole before applying the countersink, and run at manufacturer-recommended speeds for the material being machined. Wear appropriate eye protection when operating rotary cutting tools.
