M8 x 1.25 Combination Drill Tap Bit

This two-piece set combines drilling, tapping, deburring and countersinking in a single step for M8 x 1.25 threads. It is aimed at mechanics and fabricators who need to create threaded holes in metal or hard plastics without changing tools between operations.

Titanium-Coated High Speed Steel 4341 Construction

The bits are made from High Speed Steel 4341 with a titanium coating that improves wear resistance, hardness and corrosion protection while reducing friction. A 1/4-inch hex shank with a tapered end fits quick-change chucks securely and helps prevent over-tapping during use.

Check Shank Compatibility and Lubrication Needs

Verify that your drill or driver accepts a 1/4-inch hex shank before ordering. The manufacturer recommends using tapping oil for higher thread quality and longer tool life, and suggests tap collets with overload protection for machine-tapping applications.

Questions about this item

What does the 1/4-inch hex shank limit in practice?

The 1/4-inch hex shank fits standard quick-change chucks on drill drivers and impact drivers, capping use to tools that accept that shank size.

What physical dimensions must the workpiece and tool clearance accommodate?

Each bit has a 25 mm drilling length and 56 mm total length, so the workpiece must allow at least 25 mm hole depth and the tool needs 56 mm of spindle clearance.

How are these bits installed, and what step do users often miss?

Insert the hex shank fully into the quick-change chuck until it locks; the step often missed is applying tapping oil before starting to cut threads.
