Hertel 87015 Plug Hand Tap 3/4-10 Unc 4 Flute Hss

Product Description

The HERTEL 87015 is a 3/4-10 UNC plug hand pulley tap designed for threading operations in metalworking and industrial applications. Built from high speed steel with a bright finish, this tap produces unified coarse threads in through-holes and blind holes where a plug chamfer lead is appropriate. The 4-flute design provides balanced cutting action and chip clearance during hand or machine tapping. An H3 thread limit holds tight tolerance control on the finished thread. Overall length is 10 inches, making it compatible with standard tap wrenches and tapping attachments used in production and maintenance environments.

This tap is suited for machinists, maintenance technicians, and tool-and-die professionals working with 3/4-10 UNC threaded fastener applications. It performs in ferrous and non-ferrous metals where a standard plug chamfer lead allows gradual thread engagement. Typical uses include repair tapping of damaged threads, new threading in drilled through-holes, and production runs in shop environments. The bright finish is appropriate for general-purpose cutting with cutting oil or tapping fluid applied during use.

Installation Notes

This tap is installed by machinists or maintenance technicians using a tap wrench or tapping attachment. Always apply cutting oil or tapping fluid before and during use to reduce heat and extend tap life. Ensure the workpiece is securely clamped and the tap is started square to the hole to prevent breakage. Follow applicable shop safety procedures when operating cutting tools.
