The Bordo 12 x 1mm Metric Fine (MF) Bottoming HSS Tap is a precision internal threading tool engineered for trades, machinists and workshop professionals who need to cut strong, accurate threads to the bottom of blind holes. Designed for use in medium tensile materials, this bottoming lead tap delivers dependable performance in both hand and general machine tapping applications.
Featuring a Metric Fine thread form with a 60° thread angle, this tap’s flat crest and generous root clearance promote excellent engagement between external and internal threads while enhancing thread strength thanks to a larger root radius and lower thread height. The bottoming lead (two-thread lead) ensures minimal thread run-out, making it ideal for finishing threads at full depth after using a taper or intermediate tap. Manufactured from durable High Speed Steel (HSS), this general-purpose tap is built to withstand everyday workshop use.
