Custom Chucking & Pin-Float Reamers

Chucking and pin-float coolant-fed reamers can be used on all materials. Our custom pin-float reamers are like our standard reamers, but can be made longer or shorter. Chucking reamers are a costeffective way to finish a hole. Lead angles on our reamers can be made with specific angles, which are important for micro finishes and sizing. Reamers can be made left-hand helix for through holes (coolant holes in the flutes) or right-hand helix for blind holes (coolant hole through the center of the tool).

Custom Step Reamers

Step reamers are good for multiple hole sizing and chamfering all in one step. Reamers can be made left-hand helix for through holes (coolant holes in the flutes) or right-hand helix for blind holes (coolant hole through the center of the tool).

Custom Form Tools

Form tools are used for producing radii and other geometric forms on the O.D. or I.D. of a part. Form Tools can be made:

  • From carbide or HSS
  • Coolant fed if needed
  • From customer’s tool print or part print

Custom Double Margin Drills

Double margin drills are used for tight hole tolerances and stability when cutting nonferrous materials and irons. Double Margin Drills can be made:

  • From carbide or HSS
  • Coolant fed if needed
  • From a customer’s tool print or part print

Custom Porting Tools

DouPorting tools can be made for SAE, metric, MS ports and cartridge valves with straight or Morse tapered shanks. Porting tools can be made profile sharpened or cam relieved.

Custom Key Cutters

Key cutters are good for plunging, slotting or making an internal groove in a part. Key cutters can be made with corner chamfer/radii.

Custom Key Cutters

Custom Profile Cutters

Profile cutters are used for profiling areas where many tangential positions must be met; for example, turbine roots and blades.

Custom End Mills

End mills can be used for all materials. End mills can be made to circle interpolate (multitask) where one or many diameters must be produced and with serrations for roughing and chamfer/radii.

Custom Step Drills

Step drills work well for roughing out multiple holes.

Custom Saws & Milling Cutters

Custom saws and milling cutters are good for use on all materials and are used for slotting, circle interpolating and grooving. They can be made with corner chamfer/radii and with equally or unequally spaced flutes (reduced harmonic chatter).

Custom Tapered & Radius Tooling

Tapered and radius tools produce radii and other geometric forms in and on the outside of a part. Tooling includes reamers, end mills and spherical cutters.
