DRILLING (SOLID CARBIDE)
MPS
Features
aWave type cutting edge for superior drilling performance
aDouble margin flute for higher accuracy holes
aAvailable for drilling depths up to 40xD
Cutting edge shape Cross sectional shape
Wave type cutting edge Large R part
Small R part
The wave edge design achieves
sharp peripheral edge cutting
performance with a strong initial
cutting point near the centre.
Double margin flute type (MPS) Flutes of top edge
The double margin type flute Small R geometry generates initial
design provides stability and curling of the chips and combines
higher accuracy holes. with the larger R geometry to
promote smooth chip evacuation.
Excellent chip discharge Material technology
A special geometry at the top of the flute allows for Long tool life MIRACLE coated VP15TF
superior chip control.
