Titan Usa TT70707 Combination Drill Tap 8-32 Hss

Product Description

The TITAN USA TT70707 is a combination drill tap designed to drill and tap a hole in a single operation, eliminating the need for separate drilling and tapping steps. It cuts an 8-32 UNC thread with a right-hand flute direction and right-hand thread orientation. Built from high-speed steel with a bright uncoated finish, it features a straight shank, 2 flutes, and an H3 thread limit with a Class 2B fit. The overall length is 2-5/32 inches, with a drill diameter of 0.136 inches, a drill length of 13/32 inches, and a thread length of 1/2 inch. This tool is suited for machinists, maintenance technicians, and tradespeople who work with threaded fastener installations in moderate-hardness materials.

The TT70707 is used in applications requiring 8-32 UNC threaded holes in a single pass, common in electrical enclosure fabrication, panel work, HVAC equipment assembly, and general mechanical maintenance. The 2-flute geometry provides adequate chip clearance for through-hole and blind-hole applications in steel, aluminum, and similar materials. Its compact OAL and straight shank make it compatible with standard drill chucks and CNC toolholders used in light machining and field service setups.

Installation Notes

Installation should be performed by a qualified machinist or trained technician familiar with tapping operations and cutting speeds for the workpiece material. Ensure the workpiece is securely clamped before beginning and use appropriate cutting fluid to extend tool life and improve thread quality. Power down any machine tool and confirm it is fully stopped before installing or removing the tool from the chuck. Follow shop safety practices and applicable facility guidelines when operating rotary cutting tools.
