Greenfield Threading
Greenfield Threading M3.5 x 0.6 Straight Flute Hand Tap pneumatic accessory
M3.5 x 0.6 metric straight-flute plug tap in TiN-coated high-speed steel, 50.8 mm overall with 17.46 mm thread length for 75 % thread depth using a 2.90 mm drill
- Metric M3.5 x 0.6 thread for precise component fastening
- High-speed steel with TiN coating resists wear during repeated use
- Plug chamfer starts threads cleanly in through or blind holes
- 8 mm overall length gives controlled leverage by hand
- 75 % thread drill size 2.90 mm ensures accurate hole preparation
Thread size M 3.5 x 0.6
This straight flute hand tap cuts metric threads with a 3.5 mm major diameter and 0.6 mm pitch. It is designed for general-purpose threading in maintenance and light production environments. The plug chamfer suits through holes and blind holes with adequate clearance. Right-hand cutting direction matches standard fastener conventions.
High-speed steel with TiN coating
The tap body is high-speed steel coated with titanium nitride for improved wear resistance. TiN reduces friction during cutting, which helps manage heat and extends tool life in normal use. A 75 percent thread depth and 2.90 mm drill size are specified for the prepared hole. Class of fit 2B and thread limit D4 define the tolerance band.
Sustained threading in tougher materials
Under continuous use the TiN coating maintains lower cutting temperatures compared with uncoated taps. The straight flute geometry evacuates chips in short bursts, so periodic reversal is needed to prevent packing in deep holes. Overall length of 50.8 mm and thread length of 17.46 mm limit reach in confined workpieces.

Questions about this item
How do I install the M3.5 x 0.6 straight flute hand tap in a pneumatic tool holder, and what step is commonly missed?
Secure the tap squarely in the chuck, apply cutting fluid, and start the hole with the 2.90 mm drill size for 75 percent thread engagement; the step often missed is verifying the drill size before tapping.
What maintenance or replacement will the M3.5 x 0.6 tap need after extended use?
The high-speed steel cutting edges with TiN coating will gradually dull; replace the tap when threads show tear-out or when torque rises noticeably during the 17.46 mm thread length cut.
What limit appears first when running the M3.5 x 0.6 tap continuously in production?
Heat buildup in the high-speed steel body during repeated 50.8 mm overall-length cuts reduces edge hardness, so cutting speed must be lowered before the TiN coating degrades.
