CASE HISTORY for Style #293
Material: 316L Stainless Steel
Machine Type: Vertical CNC Mill
Lubrication Type: 200 PSI Soluble oil through the hole
Tool Diameter: .2165"
Hole Depth: 1.1"
SFM: 135 (2382 RPM)
IPM: 5.5 without pecking
Spot: Yes 140°
Tool life per Regrind: 180" (165 holes)
Prior Process: Former tool life on cobalt H.S.S. was 15 holes running 55 SFM x
1.75 IPM.
| Results: With CJT S.C.
Kooltwist customer is able to machine the holes (55 holes) in the part in 20 minutes
versus 60 minutes with cobalt. In addition the CJT process eliminates 15 minutes of manual
hole deburring per part. Total savings 55 minutes per part. |

CASE HISTORY for Style #294
Material: Inconel 718, 35 Rc
Machine Type: Vertical CNC
Lubrication Type: 100 PSI Soluble Oil
Tool Diameter: .2362" [6.0 mm]
Hole Depth: .93" thru
Spot: 150°
SFM: 75 (1769 RPM)
IPM: 2 (.0154 IPR)
Tool life per Regrind: 55 holes
Prior Process: Solid carbide 135° point twist non-coolant fed with peck
drilling at 50 SFM x 1 IPM. Standard solid carbide lasts 9 holes.
| Results: CJT drill
produced a part in 1 hour versus the other brand drill which required 3.5 hours and 5
times as many drills. |

CASE HISTORY for Style #294
Material: G3500 Cast Iron
Machine Type: Vertical CNC
Lubrication Type: 200 PSI Synthetic Coolant
Tool Diameter: .3150" [8.0 mm]
Hole Depth: 1.25" Thru
SFM: 300 (3638 RPM)
IPM: 43
Tool life New: 3600 holes and 3500 holes on regrinds
Prior Process: Other brand of solid carbide coolant feeding drill blows out
casting after 700 holes at similar IPM. Solid carbide square (Bore) drill runs only 8.5
IPM.
Results: CJT #294 drilled 5
times as many holes as the
coolant fed drill and 5 times faster than the non coolant fed carbide drill. |
