FANAR MASTERTAP M14 DIN 376 Form C R45 (6H) HSSE-PM HL Spiral Flute Tap

When standard taps clog and snap in high-volume through-hole work, the FANAR MASTERTAP M14 takes over with a 45° right-hand spiral that pulls chips backward out of the hole. The HSSE-PM powder metallurgy base, enriched with cobalt, keeps the cutting edges hard and tough under automated production loads. An HL surface treatment reduces friction and adhesion, so the tap runs cooler and lasts longer in steel, stainless steel, cast iron, and non-ferrous metals.

Highlights

• Metric coarse thread M14 × 2.0 mm to DIN 376, Form C lead-in (2–3 threads) for easy starting and alignment.
• Precision-ground 6H tolerance ensures consistent thread quality across demanding materials.
• 45° right-hand spiral flute optimised for through holes, efficiently evacuating chips away from the cutting zone.
• Reinforced shank (Ø11.0 mm) with square drive (9.0 mm) provides secure clamping and torque transmission.
• HL surface treatment reduces friction and adhesion, extending tool life and improving surface finish.

In daily use

Set up the tap in a rigid machine holder, align with the pre-drilled core hole, and apply appropriate cutting fluid for the workpiece material. The Form C lead-in guides the tap smoothly, while the spiral flutes keep chips flowing backward, preventing re-cutting and thread damage. Recommended for through holes only; for blind holes, consider a spiral point or straight flute tap.

Final note

The MASTERTAP M14 is built for shops that push taps to their limits in through-hole production. Its chip-evacuating geometry and wear-resistant substrate keep threads clean and tool changes rare.
