Walter – Titex & Walter – Prototyp can offer “sprint spiral flute taps” for high speed production tapping as well as Synchronised or non - Synchronised taps for appropriate feed rates on CNC machines.Ĭold form taps (roll form taps) or (flute less taps) are all the same HSS taps which actually cold form or forges the thread into a hole. The spiral flute & ground cutting edges creates the swarf to come back out the hole in controlled spiral swarf (like pigtails), this swarf evacuation allows no clogging & breakage of taps in the hole. The spiral flute tap is best suited for “blind holes”. Spiral taps are also machine taps suited for lathes, drills & mills. Most taps run at about 5 m/min however better quality Walter – Titex & Walter – Prototyp taps can run about 13 m/min or even up to 45m/min for their powder-metal “sprint” taps in steels. Gun taps can be used easily in lieu of hand taps, as the gun tap has an intermediate starting lead, only one tap is required & no backing off the gun tap is required, just keep the tap moving in a forward direction.īest suited for tapping in lathes, drills & mills, a tapping head is the ideal scenario with auto reverse & clutch to prevent breakage. This reduces friction & heat of swarf binding on its way out therefore being a very strong tap. Gun nose taps are a ground machine tap best suited for “through holes” as gun taps push the swarf thru the hole. White banded shanks best suited for cast irons Yellow banded shanks best suited for aluminium Green banded shanks best suited for all steels etcīlue banded shanks best suited for stainless steel & tool steels Machine taps are offered with coloured banding to denote what material it is best suited for. Long & extended length machine gun nose & spiral flute taps are readily avail.ĬLICK HERE TO GO TO “ Walter - PROTOTYP & TITEX” TAPPING CATALOGUES. Walter-Prototyp & Walter-Titex are German world leaders in taps & have a huge range of machine taps avail, including solid carbide taps tapping up to 60RC hardened steels & thru. The “combination drill-tapper” is handy for one quick operation mainly in sheet metal work.ĬLICK HERE TO DOWNLOAD THE “GOLIATH” CATALOGUEĬLICK HERE TO DOWNLOAD TECHNICAL INFORMATION These “serial taps” are also avail as well from Miller’s Tooling.ĭrill / tap sets, tap & die sets as well as gun taps or spiral tap sets are avail in kits to suit most thread forms. These are a series of hand taps with a profile similar to ACME thread, the taper tap is of a minimal diameter, inter tap has a slightly larger diameter, and then the bottoming tap has a finishing diameter. Not as common, in Australia, are the European hand taps known as a “serial tap set”. Most tap sets or individual taps are stocked at Miller’s Tooling Pty Ltd. Using all 3 taps in series, tapping by hand, produces the tapped hole. Hand tap sets contain x 3 taps taper (starting), intermediate & bottoming (plug) taps. The more reliable & suitable for serious engineering is High Speed Steel (HSS) taps. Hand taps can come in “carbon – alloy steel”, a cheap, one off type. Metric Coarse & Fine, UNC, UNF, BSW, BA, BSPT(Rc), BSPF(G), NPT,Ĭycle threads, B.S.Brass just to name a few, even Left Hand or custom made taps are easy to source from us. There is an enormous range of taps available at Miller’s Tooling.
