The Wimberley Toolholder - Accessories   

The inexpensive high speed steel tool bit is easy to sharpen. The toolholder's built-in back and side rake allow for efficient cutting in a variety of materials including steel and aluminum. Facing and turning can be accomplished with the holder in one orientation. This ensures that a very sharp edge is always just a few minutes and cents away.

Free samples are available to those in positions of high visibility such as authors published in The Home Shop Machinist or similar magazines.

Wimberley Toolholder ($59.00)   

"Regular cuts, facing, and turning to a shoulder, were all accomplished to my high satisfaction, all without changing the orientation of the cutter. This is superb!"
 -Glenn M. Schultz


"No resetting the tool block. No regrinding for a chip breaker. No fancy edge re-sharping angles for the edge grind. I personally think you have a winner."  
-Herbert Yohe


"Grind two facets, set the length and height, and start cutting. For the novice or experienced pro this tool will do a great job. Perhaps my highest recommendation is that I will buy others."  
-C. H. Sherin

Accessories

We sell 3/16 inch high speed steel (M2) tool bits for the convenience of our customers. These bits can be purchased less expensively from a variety of other sources including MSC, McMaster-Carr, Shars, and many others. M2 high speed steel is relatively easy to sharpen and will handle all routine machining needs. Cobalt-bearing high-speed steels such as M42 and T15 may be appropriate for more difficult-to-machine materials, but they are harder to sharpen. They are also commonly available from sources such as those above.

The toolholder comes with a bit that is ground on both ends. One end is ground to provide a positive lead angle of 45 degrees for both turning and facing (this unconventional geometry has two noses). The other end is ground to provide a -5 degree lead angle, for turning, facing, and creating a shoulder. We do sell ground bits separately, but the diligent amateur machinist should be able to set up a sharpening device such as a bench grinder or disk sander, and create and sharpen his or her own bits without great effort. We will be perfectly content if we never sell a ground bit except with a new toolholder.

One of the essential characteristics of the Wimberley toolholder is that very little material is required to renew the edge. Therefore, if you think you're going to take a long time to develop your sharpening skills, you can rest assured that you still will probably not grind away much of the tool bit. If you buy a single toolholder and want an extra unground bit to practice on, that may make sense. You probably won't need much more than this, however.
