"Tungaloy Corporation has introduced TetraMini-Cut that provides high precision and quality in grooving and threading of small parts," said a company spokesperson.
The TetraMini-Cut's ground insert, with four corners, is suited for high-precision and high-quality machining of small parts. The insert pocket protects unused corners from chip damage during machining, thus assuring the usage of every corner of each insert. "A unique clamping system provides high rigidity and excellent index repeatability," said the spokesperson.
It is also suitable for undercutting the shaft along a flange wall. The insert screw can be tightened either from the front or the back of the toolholder, which simplifies the operation when mounted in a Swiss lathe.
Grooving inserts with widths from 0.013" to 0.118" (0.33 to 3.00 mm) are available in SH725. The new versatile PVD coating helps prevent loss of sharpness of the cutting edge. Threading inserts with pitches from 0.031" to 0.118" (0.8 to 3.0 mm) are available in AH725 PVD grade for a wide variety of materials, such as steel, stainless steel, cast iron and heat-resistant alloys.
Main features:
- Economical four-cornered insert
- Clamping system for highly rigid insert clamping and tool durability
- Insert pocket designed to protect unused corners from chip damage during use
- Capable of undercutting and finishing a flange wall at the same time when grooving on the shaft along the flange wall
- Both grooving and threading inserts are available.
"Tungaloy has also introduced an addition of the honed-edge inserts to the AH725 TetraMini-Cut insert series, which adds extra durability on the cutting edge for high-precision and high-quality grooving," said the spokesperson.
The cutting edge on this AH725 PVD grade insert is honed to increase toughness against chipping. To complement the sharp-edged SH725 insert, the honed-edge AH725 insert is designed to improve stability in high-load machining such as roughing, high-feed cutting and interrupted cutting.
