Cleveland C86149 Spiral Point Tap M16x2 Cobalt TiAlN

SKU CH-HZQ8-56HK1

Cobalt spiral-point tap cuts M16×2 metric threads in through-holes, TiAlN-coated for wear resistance

  • M16x2 metric thread cuts cleanly in tough alloys
  • Cobalt substrate with TiAlN coating resists heat and wear
  • Spiral-point design pushes chips ahead for smooth through-holes
  • Three-flute geometry balances strength and chip clearance
  • 110 mm overall length reaches deep or awkward holes

Cleveland C86149 Spiral Point Tap M16x2 Cobalt TiAlN

The Cleveland C86149 is a spiral point tap designed for through-hole threading in metric M16x2 sizes. It suits machinists and maintenance technicians who need reliable chip evacuation forward during tapping operations. The cobalt substrate with TiAlN coating supports extended tool life in steel and stainless alloys. This tap is not for blind holes or applications requiring bottoming-chamfer engagement.

Thermals noise and power draw

As a hand or machine-driven cutting tool, the tap generates heat only at the cutting interface during use. No electrical power is consumed and no audible noise is produced beyond normal machining sound. Cutting fluid or lubricant manages temperature at the thread zone effectively. The TiAlN coating reduces friction and wear without adding thermal load to the system.

Thread specification M16x2 6H class of fit

The tap cuts a metric M16x2 thread to a 6H class of fit with a 75 percent thread depth based on a 14.00 mm drill size. Thread length is 53.01 mm on an overall length of 110 mm with three flutes and a plug chamfer. Right-hand cutting direction matches standard fastening requirements. Select this tap only when the hole size, thread pitch and fit class match these exact parameters.

Questions about this item

How do I install the Cleveland C86149 tap and what step is often missed?

Drill a 14.00 mm hole first, then run the tap with proper lubrication; the step many skip is using cutting fluid to prevent cobalt edge chipping.

What maintenance or replacement will the Cleveland C86149 tap need later?

The TiAlN coating wears gradually; when threads show oversize or surface finish degrades, replace the tap — resharpening removes the coating and changes the 6H limit.

What limit appears first on the Cleveland C86149 under sustained use?

Heat buildup in the 53.01 mm thread length softens the cobalt substrate, causing flank wear that exceeds the 6H tolerance before the spiral point clogs.
