K20C is our standard stocked grade and satisfies the greatest range of material applications. K20C should be the first choice for most applications. grade is a TiAlN (Titanium Aluminum Nitrade), PVD coated grade recommended for difficult to machine alloys having work-hardening or abrasive wear characteristics. K27C could improve wear life in materials such as stainless steels, nickel alloys, most cast irons as well as graphite resin composites. There are 3 critical steps required for optimizing a thread milling operation for any thread to be produced.

Drill Recommendation For Thread Milling NPT & NPTF Threads Thread Size Drill Size Dec. Diameter Production of full form internal or external NPT or NPTF threads by thread milling requires changing the minor diameter of the bore or the external major diameter 1/16-27 B prior to the final thread milling process. 1/8-27 1/ /64" 27/64" Do not refer to tap drill charts for internal pipe tap 3/8-18 9/16" applications. The internal minor diameter created using 1/ mm tap drill sizes will truncate the minor diameter crest 3/ mm beyond the maximum allowable limits with the exception 1" /8" of two turns from the end of the pipe. 1-1/4" /2" The chart to the left recommends the ideal drill size for 2" preparing the bore of an internal pipe thread milling 2-1/2" application prior to taper reaming or before going 3" straight to the thread milling operation without reaming 3-1/2" the taper. This will produce full crest and root form 4" threads to the L3 gage line. CNC Programming Data For NPT & NPTF Threads Pitch 28 & & & 11 8 Compensations Per 90 Of Arc " " " " " To produce accurate tapered threads for any pipe thread application having a 1:16 or 3/4" per foot taper, the CNC program must incorporate an increase in arc radius as the centerline of the thread to be produced. For straight threads, a 360 arc move is made around the center with a Z positive move up one pitch. If this were used for pipe threads, the end result would be an oval thread because the 1-47' 24" taper ground on the tool cutting edge will move away from the pitch diameter as the tool moves up. To create a perfect pitch truncated cone pitch diameter for pipe threads, the X & Y arc tool path must also increase to match the taper of 1-47' 24" as the tool moves up the bore one pitch. This cannot be performed in one 360 G code line. The use of 4 separate lines using 90 of arc move are required. An ever increasing arc radius is incorporated based on the distance moved up (1/4 pitch) in Z. The end points of each arc move must also include this additional increase in X or Y. The chart above indicates the exact amount of compensation required for each 90 arc move. 23
