A set of 6 combined drill tap bits designed to drill and tap a hole in a single pass. Each bit has been manufactured from high speed steel (HSS) with a Titanium-Nitride coating for hardness, rust resistance and longevity. The tap bits feature a drill section at the end of each bit which forms the perfect sized tap hole in the material for the following tap section to then cut the threads into, together with spiral flutes to clear the swarf created; plus a deburring shoulder to ensure the edge of the hole is finished without any sharp edges. The set also includes a 60mm long magnetic bit holder with a quick-chuck end for ease of use.
- 6x tap drill bits with 1/4" Hex drive: M3 x 0.5 (max 400rpm), M4 x 0.7 (max 400rpm), M5 x 0.8 (max 350rpm), M6 x 1.0 (max 300rpm), M8 x 1.25 (max 250rpm) and M10 x 1.5mm (max 200rpm). NOTE: The max rpm is a guide for use on wood and plastic only.
- Supplied with a magnetic bit holder. Length: 60mm.
- Suitable for drilling and tapping iron or carbon steel plate up to 3mm thick and aluminium or copper plate up to 6mm thick.
- Bits manufactured from HSS4241 with Titanium-Nitride coating and quick chuck ends. Supplied in a storage case.
- Spares available, Part Nos. 61871 (M3 x 0.5mm), 61872 (M4 x 0.7mm), 61873 (M5 x 0.8mm), 61867 (M6 x 1.0mm), 61868 (M8 x 1.25mm) and 61869 (M10 x 1.5mm). Note: manual tapping is not recommended, as this will affect the precise concentricity and adversely affect the product performance life.

Let customers speak for us
Nice compact piece of kit that doesn’t clutter up the tool box too much. Really easy to use and ensures chain is running true .I should’ve bought one years ago!!
Excellent tool for precise measurements and a good price.
Firstly the product represents good value and is perfect for my needs. Ordering was easy, communication was brilliant and delivery was trouble free. Thanks for the sticker and the Haribo nice touch
Really pleased with this tool. Well made and robust and first class quality.
A really decent measuring instrument. A good quality "feel' to it. Also a nice box to keep it in, stop it rattling around in your toolbox. Not just a cheap thin plastic wallet. I will be keeping and using this for a long time.
Strangely though, it has NO vernier scale, and so is not really a VERNIER caliper. Strange but true!
Very happy with the vernier calipers, and quick delivery.
Ralph does it again…….i cannot praise Bikers Toolbox highly enough. I buy all my tools from Ralph, simply because he truly deserves our business. Proof again with the Digital Vernier Caliper I recently bought from him. Top quality tools that he is prepared to pass on for a price that is an absolute bargain, he genuinely doesn’t need to offer these prices, but the fact he does is absolutely gold in the motorcycle community. Thanks!!!
Haven’t used them yet but they look good..
Spot on, super quick delivery. Thanks for the complimentary chew 😁 I will come straight back to you if I need more tools, especially for my older bikes
I've bought them to work on Japanese carburettors
