Carbide Insert
August 6th, 2011
Difficult-to-machine materials?
I wish to test a hard coating on simple geometry tools (e.g., indexable carbide inserts). Can anyone recommend a material and machining operation which should readily wear standard cutting tools (e.g., inserts, taps, router bits)?
I’m looking for a simple set-up which will readily wear a tool — for example, fly cutting copper, or turning G-10.
I would use what was locally available at reasonable cost. I like lathes best. Chose one with high power to speed test. In the old days, people ran machines slowly to maximize tool life, thinking they were minimzing cost. Now, smart shops run at high speeds, as tool cost is not so significant compared to other costs.
4130 forged bar is a great material for testing. Mediocre machinability, good strength, some degree of hardness, not too expensive. But I think you could use plain carbon steel bar or pipe just as well. It probably requires about 2x more material for similar wear.
But what do you mean when you say hard to machine? I don’t think you mean exotics that give nasty surface finish.
Be careful doing your test and controls. I would claim that tool temperature is a primary wear predictor. Hard to keep this consistent between tests, or even to measure it.

Carbide Sight Insert Cutter Carbide Sight Insert Cutter $71.99 We’ve had many requests for a small dovetail cutter that would speed up the cutting of dovetails in front sight blades when installing colored inserts. The one we’ve had made cuts a 1⁄4" wide dovetail just right for sight inserts and the finished product is very precise. Since the cutter is small (it tapers to a diameter of .110") you must make an initial cut with a 1⁄8" end mill (listed below). By using the end mill to remove some metal first you’ll avoid overloading the cutter and breaking it. CAUTION: For use in milling machine only. Solid carbide 2" (5cm) long. 1⁄4" (6.3cm) diameter shank. 60° shoulder. Mfg: Brownells |

GERBER 48252 Carbide Insert Replacement Kit for 800 Legend $29.12 Selected models of the Gerber tool line feature an extremely rugged tungsten carbide cutting insert. This triangular insert is particularly good for cutting wire or fishhooks or other similar materials. And because you ll be inclined to use the heck out of this cutter we figured it d smart of offer replacements. Carbide Cutter Insert Replacements come two to a pack and include a hex head wrench and four replacement screws for MultiPlierr tool itself. It might be a good idea of keep a replacement pack on hand. Because you just never know when you re encounter a whole lotta things that just beg to be clipped with the power of tungsten carbide. These inserts cut quick and clean and mean. Two tungsten carbide cutter replacements. Hex head wrench. Four replacement screws. |
