GUHRING HSS-E PM TiCN-CO Coated Thread Form Tap #4-48 UNF Chipless Extrusion Tap for Stainless & Carbon Steel Cutting Tap Carbide tools CNC Tools
Product Overview
The GUHRING Series 3944 #4-48 UNF TiCN-CO Thread Forming Tap (Form Tap) is a high-performance chipless forming tap manufactured by Germany GUHRING, built with premium HSS-E PM cobalt powder metallurgy substrate paired with advanced TiCN-CO composite anti-friction coating. Unlike cutting taps, this thread form tap extrudes material to form precise internal UNF threads without chip generation, eliminating chip jamming risks entirely. Designed for #4-48 fine UNF thread mass production, it delivers superior surface finish, high thread strength and extended service life on ductile metals including carbon steel, stainless steel, low alloy steel and non-ferrous alloys, fully compliant with ANSI & DIN dual industrial standards.
Key Features

GUHRING Series 3944 UNF Cobalt TiCN-CO Thread Form Tap
Nominal Thread Size
#4-48 UNF (0.112 inch major diameter, 48 threads per inch fine pitch)
Base Raw Material
HSS-E PM Powder Metallurgy Cobalt High Speed Steel
Non-ferrous ductile metals: Brass, copper, aluminum alloys, zinc die castings
Soft ductile ferrous & non-ferrous components prone to built-up edge
Typical Applications
Chipless precision UNF internal thread forming for #4-48 small fine pitch fastener parts
CNC machining center, automatic lathe high-volume mass threading production
Electronic hardware, automotive small fittings, hydraulic miniature component manufacturing
Medical equipment precision small threaded parts requiring smooth burr-free thread surface
Batch production where chip removal and thread burr defects need full elimination
Advantages of GUHRING Series 3944 TiCN-CO Form Tap
HSS-E PM cobalt powder substrate: Higher heat resistance and wear resistance than conventional HSS-E, withstands continuous high-speed forming loads without tap chipping
TiCN-CO carbon composite coating: Ultra-low friction coefficient effectively suppresses material adhesion and built-up edge, greatly extending service life vs standard TiCN coated taps
Chipless forming design: No chips generated during machining, eliminates chip clogging, scratching and thread damage issues
Extrusion thread strengthening: Cold extrusion process compresses thread grain structure, improving internal thread tensile strength and fatigue resistance by 20%+ compared to cut threads
Optimized semi-bottom chamfer: Smooth penetration into workpieces, balanced forming load for stable dimensional consistency
Germany precision multi-stage cold forming & grinding process, consistent thread size repeatability for long batch runs
