M8-1.25 coarse thread tap
The Westward 2LWP8 is a straight-flute hand tap for cutting M8 by 1.25 metric coarse threads. Made from high-speed steel with a bright uncoated finish, it suits general-purpose threading in maintenance and light production. The taper lead eases starting in through holes or deep blind holes. Right-hand cutting direction matches standard fastener threads.
Taper lead distributes cutting load
Four flutes share the chip load so each tooth takes a lighter cut during sustained threading. The taper chamfer engages gradually, reducing peak torque compared with plug or bottoming styles. High-speed steel retains hardness at the temperatures reached in hand tapping or low-speed machine work. Chip evacuation relies on the straight flute geometry and periodic reversal.
Uncoated surface needs lubrication
Bright finish provides no built-in lubricity, so cutting fluid or paste is essential to manage heat and prevent galling. Hand operation keeps power draw low and noise minimal compared with powered tapping. The 11/8 inch thread length limits the maximum depth in a single pass. D5 class of fit suits standard nut and bolt assemblies.

Questions about this item
How much torque or heat builds up when running the M8-1.25 taper tap all day in steel?
The high-speed steel body resists heat during extended threading, and the straight-flute design clears chips efficiently to keep cutting forces steady.
What holder or wrench must I already own to turn the 2 23/32 in tap?
A standard M8 tap wrench or T-handle that fits the square shank is required; no special adapter is needed.
Will the D5 thread limit cut cleanly in an older drilled hole that may be slightly undersized?
The D5 limit provides standard-class fit for metric coarse threads, so it matches holes drilled to the correct M8 tap drill size.
