ULTRA Coated Cutters - Data Sheet
BEST PRACTICE ADVICE
GUIDELINE PARAMETERS ONLY - Actual parameters may vary depending on operating conditions
ULTRA Cutting Tools are designed for the Machining of Armor and Wear Plates such as
HARDOX - CREUSABRO - ABRO - RAEX - STRENX - BISALLOY
1. The extreme hardness and resistance of wear plate makes machining it extremely challenging.
2. Good results are dependent on the right setup - including high torque/slow speed, geared Magnet Drills, such as
the VersaDrive® V125T, and correct lubrication
3. Using an incorrect or poorly maintained Magnet Drill with unstable drilling operation, poor magnet hold,
excessive pressure or inadequate lubrication is likely to result in rapid tool failure.
4. Even with high tech tooling, successfully machining Wear plates is challenging with little or no margin for error. It
not only requires the correct setup but also experienced operators with the time necessary to proceed with caution.
5. Feed should be applied constantly, do not allow the drill to dwell as the material will work harden
(if a rest or repositioning of hands is required, then retract the cutting tool slightly o昀昀 the material 昀椀rst)
6. When drilling hard materials drill required hole size in one operation - do not attempt to pilot drill & step up
through drill sizes
7. When cutting, any rubbing of the cutting tool must be avoided as it will increase the surface hardness, as wear
plate material is designed to 'work-harden' to combat wear and abrasion
8. When using a 2-Geared Speed or 4-Geared Speed drilling machine, the lower gear speeds provide the most
torque
9. When using the electronic variable speed and torque controls, maximum torque and power is available when
both torque and speed are adjusted to their maximum setting
10. Machines 昀椀tted with torque control will try to maintain the selected speed and slow slightly, when under load
11. Regular application of lubricant and removal of swarf from the cutting face is essential
12. A hand brush is helpful to keep excess swarf away from the cut
13. Constant coolant application is advisable to carry away any heat generated by cutting, as heat build up can
cause work hardening.
14. For best results use the new 昀氀ood coolant pump with a soluble mix of BioCut Blue lubricant & room temperature
tap water.
Suggested mix: 1/8 Gallon of BioCut Blue to 7/8 Gallon water
15. If a 昀氀ood cooling system is used, consider there will be excess coolant spillage
16. For best result when countersinking, the countersink should be piloted where possible - see MultiSink pilots on
page 95
17. Do not allow the countersink to vibrate over swarf while cutting as this will cause chatter, ultimately causing the
cutting edge to chip & blunt
