Hand taps for blind-hole threading, designed to deliver clean, repeatable threads in metal and plastic. Rennie Tool Company Spiral Flute Tap Pack combines M2 HSS construction with a TiN coating and spiral flutes to improve durability and chip evacuation. Are these taps up to the demands of professional and DIY blind-hole work?
⚡ At a Glance
- • Cutting Quality: Sharp M2 HSS cutting edges with TiN coating for clean, precise thread profiles
- • Best for: Workshops and DIYers tapping blind holes in metals and plastics
- • Not ideal for: Through-hole tapping where straight flutes or bottoming taps are preferred
M5 x 0.8mm spiral flute taps supplied as a three-piece pack. Spiral flutes draw chips out of blind holes and a self-centring point helps start threads accurately.
Clean, accurate threads - With M2 HSS cutting edges and TiN coating
M2 high speed steel retains a sharp cutting edge under cutting temperatures, while a titanium nitride coating reduces friction and improves surface hardness to slow wear.
Neat thread profiles emerge with minimal burrs, and taps last longer across repeated jobs, reducing replacement frequency.
Efficient chip evacuation for blind holes - Thanks to spiral flute geometry
Spiral flutes lift chips back out of blind holes rather than packing them at the tip, lowering the chance of clogging and breakage during deep tapping.
Fewer stoppages and less risk of snapped taps when working on deep or enclosed holes, speeding up batch or repair work.
Faster set-ups and accurate starts - With a self-centring point usable by hand or machine
A self-centring point helps align the tap with the drilled hole so pre-centring is often unnecessary, and the taps are rated for use by hand or in a machine.
Reduced preparation and fewer alignment errors lead to quicker, more reliable tapping, especially useful where repeat accuracy matters.
