A Big Cut Above the Others

Most knurling tools merely 'push' material (as in cold forming) and require heavy machining forces. These tools are generally limited to softer materials with small work diameters.

Keyway Tooling incorporates superior grades of steel and heat treatment and their knurling tools are engineered to actually CUT the material! This reduces stress and strain on the tooling as well as the machinery, permits longer production runs without retooling and produces a high quality product.

Knurling tools from Keyway Tooling perform aggressively and will cut any commonly machineable material. They can be used for producing small and large diameter knurls.

EFFICIENT cutting increases productivity

VERSATILE wider use of each tool reduces tooling inventories

DURABLE longer tool life greatly reduces costs

RUGGED cut diamond-pattern knurls to 1/2" pitch

INNOVATIVE initially developed for knurling feed rolls in the demanding pulp and paper and sawmill industries

Setup Instructions

  1. Turn the outside diameter of the workpiece true and parallel.
  2. Rotate the knurling head to the appropriate angle (30 or 45). Install the lock pin and tighten both screws.
  3. Set the compound slide to 7, according to the carriage direction. (See Figures 1 and 3) Knurling will start at the tailstock end of the workpiece.
  4. The first knurling wheel cutting tooth to contact the workpiece should be .010" to .015" below the centreline. (See Figure 2)
  5. Recommended feed: .005" to .007"
    Recommended speed: 25 to 50 RPM (depending on the diameter of the workpiece)
  6. Cutting oil or soluble coolant is required. Cutting oil is recommended
  7. Start knurling but consider the rigidity of the toolpost and lathe before attempting a full depth cut.
  8. Reverse the procedure, resetting the compound slide according to the carriage direction, and cut from the Figure 2 headstock end of the workpiece.

  • Keep the knurling wheel sharp at all times to prevent a helix from forming on the workpiece.
  • We suggest adding 1 to 2 inches of extra length at the start of the workpiece to create a running start into the finished cut, if possible. Remove the extra material when the knurl is completed.
  • New users should run a few familiarizing test set-ups before undertaking finished work.
