* General Recommendation

Above suggested parameters are recommended for uncoated carbide drills only.  For coating tools, Feedrate SFM may be increated accordingly and these general percentages are suggested under optimal conditions:

  ALTIN = +40%

Premium Carbide Blank
 

SANDVIK H10F Carbide Blank

on size 1/4" and smaller carbide end mill

Extra-fine Submicron grain Cemented Carbide Grade for Rotary Tools

H10F grade offers an excellent combination of strength and toughness. In addition, a special additive maximize corrosion resistance without loss of toughness.  Grades with binder content in the range of 10 wt % and grain size below 1um have the highest hardness and compressive strengths, combined with exceptionally high wear resistance and high reliability against breakage.

Kennametal TCM 2210 Carbide Blank

on size larger than 1/4"  carbide end mill

Tooling from TCM is engineered to perform beyond common expectations. We manufacture from high-grade raw materials and blend our unique powder formulations to meet the most  demanding requirements of the rotary tool industry.


 CNC Grinding Machine

 

Our end mill are made using the world renowned Rollomatic CNC grinding machine.  30 sets of ROLLOMATIC CNC grinding machine from Switzerland, for manufacturing carbide e d mill from 0.1mm (0.004") to 16mm (5/8"), capable of m intaining an industrial leading tolerance of +/- .0002" 

 PVD Coating Centers

Swiss made PLATIT unit is the 'state-of-the-art' equiment in the coating industry.  With in-house Platit PL1001 Compact coating center to minimize production lead time and lowering cost, capable of applying Tin, TiCN, AlTiN, ZRN coating.
   

     PLATIT PL 1001 COMPACT

  • High capacity hard coating machine
  • Based on PLATIT's patented cathode ARC technology
  • PVD coating on HSS, Cobalt, & Tungsten Carbide
  • Highest quality and consistent coating
     PLATIT Degasser
  • Vaporizes oils or any other fluids from blind or coolant fed holes after cleaning process
  • Removes trapped gases from grzed cutting tools
  • Helps ensure proper coating adhesion
  
        EUROCOLD Pluritank is a state-of-the-art automated tool cleaning system that removes all oils and contaminants from tools prior to coating       With PLATIT's easy loading carousel tool holders, different tool types and sizes can be mixed and coated in one load to maximize cycle efficiency
   
 After coating, to help maintain our clean-room environment, a cool-down box is used to contain and remove any excess coating dust particles  We have a PLATIT quality control system that allows us to check coating thickness and adhesion. A sample piece is inspected and documented after each load of coating
