Emuge's A-H HSS Taps Designed for Hardened Steel and Cast Iron
Emuge’s A-H family of HSS-E and HSSE-PM taps was designed to provide more standard product solutions for threading hardened steel and cast iron.
Emuge’s A-H family of HSS-E and HSSE-PM taps was designed to provide more standard product solutions for threading hardened steel and cast iron in such markets as heavy equipment and agriculture. The taps are available with or without coolant-through holes and the choice of a TiCN coating or NT nitride surface treatment for improved tool life.
The HSS-E tools can tap materials as hard as 48 RC. With a hard, heat-resistant powdered metal substrate, the HSSE-PM A-HCut taps can handle materials between 44 and 55 RC. The TiCN coating enhances the taps’ surface hardness and help increase abrasion resistance. Axial coolant holes aid in chip evacuation.
The A-H family of taps is offered in a Rekord A style for through- and blind-hole applications. UNC/ UNF thread sizes along with metric and metric fine sizes are available.
Creating threaded holes in titanium alloys calls for proper techniques based on an understanding of both the properties of these materials and the peculiarities of the tapping process.
Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.
Reducing cutting fluid use offers the chance for considerable cost savings. Tool life may even improve.
