Walter USA’s TC117 and TC217 Advance taps are said to provide high threading productivity in a range of materials.
The TC117 (blind-hole) and TC217 (through-hole) taps tackle material ranging from steel to aluminum (ISO material groups P, M, K and N), including metals as hard as 370 HB. Because of this, the company states that these tools can help to save inventory costs by reducing the number of taps needed.
The TC117 blind-hole tap has a 40-degree helix angle and is available with a length of 2.5×DN 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 threading depth maximum of 3.0×DN. Both taps are made with an HSS-E substrate that provides durability because of its cobalt enrichment.
The WY80RG option provides chip control, wear resistance and higher cutting speeds. The WY80FC option sacrifices wear resistance and cutting speed but offers chip control for stringy and difficult-to-control chips such as those produced by 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).
