Waukesha, Wisconsin – Walter has announced the introduction of the TC117/TC217 Advance cut taps for high threading productivity in a wide range of different materials.

The Advance lineup is one of the three categories to Walter threading tools. The Advance line signifies product that is efficiently balanced between price and performance. The others are Perform tools that provide an economical solution with focused importance on price and the Supreme line indicating the highest level of technology and performance available.

The versatile TC117 (blind-hole) and TC217 (through-hole) taps tackle material ranging from steel to aluminum (ISO material groups P, M, K, and N), materials up to 370 HB and because of this versatility can help save on inventory costs by reducing the number of taps needed.

The TC117 blind-hole tap has a 40° helix angle and up to 2.5xDN with chamfer form C (semi bottoming) or E (full bottoming). The TC217 through-hole tap features a spiral point for forward chip evacuation and a thread depth capability of 3.0xDN. Both taps use HSS-E substrate that provides excellent durability due to its cobalt enrichment.

The new sizes include UNC thread styles, giving these highly flexible taps an even wider range of application in a variety of materials. The taps feature WY80RG for good chip control, good wear resistance and higher cutting speeds and WY80FC, which sacrifices wear resistance and cutting speeds but offers much better chip control for stringy and difficult-to-control chips such as stainless steel.

Dimension range includes UNC 1-64 to UNC 2 1/2-6; UNF 0-80 to UNF 1 1/4-12; UN 1 1/8-8 to UN 1 5/8-8; UNS 1-14; STIUNC 2-56 to STIUNC 3/8-16; STIUNF 10-32 to STIUNF 3/8-24; and M3 to M20, all offered with DIN length/ANSI Shank(DIN/ANSI standard).
