Spiral Flute Tap M3.5x0.6
This Widia Gtd spiral flute tap cuts M3.5 by 0.6 metric threads in a right-hand direction. It is made from high speed steel with a black oxide finish and has two flutes. The thread limit is D4 for a 6H class of fit. It suits machinists and maintenance technicians who need to produce internal threads in through or blind holes.
Build integration with 50.8 mm length
The tap measures 50.8 mm overall with a 9.7 mm thread length and requires a 2.90 mm drill for 75 percent thread engagement. Its bottoming chamfer allows threading close to the bottom of a blind hole. The shank fits standard tap holders or wrenches, freeing the user from proprietary tooling while the spiral flutes pull chips clear of the cut.
High speed steel and black oxide benefits
The high speed steel construction resists wear when cutting steel, stainless steel or non-ferrous metals. Black oxide coating reduces galling and helps retain cutting fluid during operation. Two flutes balance chip evacuation with core strength, lowering the risk of tap breakage compared with single flute designs. No additional accessories or software are bundled.

Questions about this item
How deep can the M3.5x0.6 tap cut threads in one pass?
The thread length is 9.7 mm, so that is the maximum depth per engagement.
Does the high-speed steel tap run hot during extended pneumatic use?
High-speed steel handles heat well; use cutting fluid to keep temperatures down during long runs.
What drill bit must I have ready before tapping M3.5x0.6 holes?
A 2.90 mm drill produces the recommended 75 percent thread for this tap.
