M2.5 Metric Tap Kit
The Greenfield Threading 343503 kit supplies three straight-flute hand taps for cutting M2.5 x 0.45 metric threads. It suits machinists and maintenance technicians who need to create or repair internal threads in metal components.
High-Speed Steel Construction
Each tap is made from high-speed steel with a TiN coating for wear resistance during hand-tapping operations. The kit includes taper, plug and bottoming styles so the user can start, deepen and finish a thread without switching tools. Breakage is the main risk if chips are not cleared frequently or if cutting fluid is omitted.
Verify Drill Size and Fit Class
Before ordering confirm that a #46 drill producing a 75 percent thread is correct for the workpiece material and that a D3 limit with 6H class of fit matches the design specification. The right-hand thread direction and 3-flute geometry must also suit the application.

Questions about this item
How can I confirm the M2.5x0.45 tap is cutting correctly after setup?
Check that the threads produced match the 6H class of fit and the 75 percent thread depth using the #46 drill size specified for this kit.
What comes in the 343503 kit and what must I supply myself?
The kit includes three high-speed steel taps — taper, plug and bottoming — each with three flutes and TiN coating; you must provide the #46 drill bit and a tap wrench.
Which version of the M2.5x0.45 tap should I choose for a through-hole versus a blind hole?
Use the taper tap to start a through-hole, the plug tap for general through-hole work, and the bottoming tap to finish threads near the bottom of a blind hole.
