Westward M10 Spiral Point Tap
The Westward 5TWL4 is a metric spiral point tap designed to cut M10 x 1.50 coarse threads in through-holes. Its high-speed steel construction and bright uncoated finish suit general-purpose threading in steel and non-ferrous metals. The plug chamfer and three-flute design push chips ahead of the cut for efficient material removal. Machinists and maintenance technicians use this tool for creating new internal threads or restoring damaged ones.
Verify Hole Size And Machine Setup
Before ordering confirm the required tap drill size for an M10 x 1.50 thread to produce a correct 3B class of fit. Ensure the workpiece material is compatible with uncoated high-speed steel cutting. The tool has a right-hand cutting direction and a thread length of 1 1/4 in within an overall length of 2 15/16 in. Check that your holder or wrench accommodates the shank and that the machine spindle runs at a suitable speed for the material.
Replaces Worn Or Incorrect Taps
This tap replaces dull, chipped or incorrectly sized taps that produce oversize or rough threads. The D6 thread limit and 3B class of fit provide tighter tolerance control than standard commercial taps. Upgrading from a taper or bottoming chamfer to this plug style improves starting alignment in through-hole applications. The spiral point geometry is not suited for blind holes where chips cannot escape forward.

Questions about this item
What comes with the Westward 5TWL4 Spiral Point Tap and do I need to buy a handle or die separately?
The tap is sold individually without a handle or die set; a suitable tap wrench and matching M10-1.5 die must be purchased separately for threading operations.
Which thread class and flute count should I choose for a standard M10x1.5 metric coarse hole?
This tap is a Class 3B, three-flute plug design for M10x1.5 metric coarse threads, suited for general-purpose through-hole tapping in steel and non-ferrous metals.
What does the 2 15/16 in overall length mean when the tap is in a wrench and cutting?
The 2 15/16 in overall length gives the distance from the shank end to the tip, determining reach in a tap wrench and the maximum thread depth possible in a single pass.
