Quality CHASERS FOR STYLE D & STYLE K DIE HEADS
Type D – For geometric, rubometric, fahrion, taco and any die heads that use geometric Type D chasers.
The standard chamfer angle is 33° on regular style chasers and 45° on projection style. This chamfer angle may be changed to suit the job, since tool life will be greatly enhanced by lengthening the chamfer and spreading the cutting load over a larger area of the chaser.
