MTECS B

Small Diameter, Short type

SolidThread MTECS is used for the production of small This unique tool design offers very precise profiles and

internal threads. These thread mills feature a high performance AH725 submicron carbide gradeAH725 C

a short 3-tooth cutting zone with 3 flutes and with PVD titanium aluminum nitride coating. a released neck between the cutting zone and The very short profile exerts a low force which minimizes the shank. tool bending. This facilitates parallel and high thread precision for the entire length.

Compared to taps, the SOLIDTHREAD is more accurate, thread machining is substantially faster and G there is no danger of a broken tap being stuck in the hole.

Features

  • Minimum thread size of MTECS: M1x0.25 (0.75 mm pre hole diameter)

up to M20x2.50

  • 2xD and 3xD threading lengths K
  • High cutting speeds
  • Short cycle time
  • Low cutting forces due to the short contact profile

resulting in accurate and parallel thread

  • Prevents oval threads near thin walls
  • No more dealing with broken taps L
  • Reliable threading in blind holes
  • Excellent performance on hardened steel,

high temperature alloys and titanium
