Spiral Point Tap M8-1.25

The Cleveland C86241 is a spiral point tap designed for creating M8x1.25 metric coarse threads in through-hole applications. It suits machinists and maintenance technicians who need reliable thread cutting in a single pass.

Cobalt high-speed steel with black oxide

Cobalt high-speed steel construction resists wear when cutting harder materials. The black oxide finish reduces friction and helps retain cutting fluid during operation. Three flutes and a 90 mm overall length provide stability and chip clearance in standard tool holders.

Plug chamfer limits blind-hole use

The plug chamfer style requires a through hole or deep clearance, so it cannot finish threads to the bottom of a blind hole. Buyers who need full-depth threads in closed cavities must choose a bottoming or modified tap instead. The 6H class of fit meets general-purpose tolerance requirements.

Questions about this item

What thread standard does the M8-1.25 spiral point tap follow, and what class of fit does it produce?

The tap cuts a metric coarse M8 × 1.25 thread to a 6H class of fit, giving a standard 75 % thread engagement.

What are the overall length and thread length of this tap, and how many flutes does it have?

Overall length is 90 mm with a 35 mm thread length, and the tool has three flutes.

How is a spiral point tap started correctly, and what common mistake should be avoided?

Start the tap square to the hole with light pressure and cutting fluid; the frequent error is forcing it at an angle, which breaks the flutes.
