Tapered Carbide End Mills for NPT/ NPTF Pipe Threads

EMUGE-FRANKEN USA has introduced a new line of 1:16 Tapered Solid Carbide End Mills designed to prepare a tapered core hole prior to finish tapping or thread milling NPT/NPT/BSPT pipe threads. The new cutters feature an innovative design that reduces the number of tools required for hole preparation over a large range of pipe thread sizes, and they extend the tool life of expensive taps and thread mills, the company reported.

"Uniquely designed with the proper 1:16 taper angle ground into the conical form for milling the minor diameter of taper pipe threads prior to tapping or thread milling, these new tools provide an enormous advantage over HSS taper reamers, offering substantial time and cost savings," said Dylan Bowles, Applications Support Specialist at EMUGE-FRANKEN USA. "These tools do not require a large or 5-axis machine tool, since smaller 3-axis machines can handle larger threading applications."

Only three EMUGE-FRANKEN Tapered tool sizes are required to handle a full range of hole sizes from 1/4" up to 4", instead of having to purchase an individual taper reamer for each pipe thread size. They also provide an efficient and secure method for optimizing thread milling strategies that incorporate the use of partial-profile insert technology.

EMUGE-FRANKEN 1:16 Tapered Carbide End Mills are engineered to work well in a full range of materials, including aluminum, carbon steels, stainless steels and exotic nickel alloys. They are made of a premium micro-grain carbide substrate with TIALN-T21 coating that resists heat, edge wear and chipping. Corner radii further prevent wear or chipping while prolonging tool life. Tools are four-fluted, feature standard U.S. length and straight inch shank (h6) and are available in three sizes: 3/8", 1/2" and 3/4".
