The document discusses the Jominy end quench test for determining the hardenability of steels. It describes how a standardized test sample is austenitized and then quenched at one end with water. Hardness measurements along the length provide a hardenability curve, with greater hardness penetration indicating higher hardenability. The cooling rate decreases with distance from the quenched end, allowing simulation of a range of cooling rates. Comparison of curves for different steels establishes their relative hardenability.Read less

The 1/4" rounding radius CNC router bit is the bit that adds elegance to your woodworking CNC project that gives it the extra character to make it stand out. Round the borders or letters. It doesn't matter, as long as you have 1/4" to play with on your project, this cutter will spice your project up.

I didn't use it yet. I bought it to build my collection, to have it handy when i may need it. I love the informative information available thru your site, and always on target. Keep it up.

The 1/4 round router with a 1/4 shank is a wood-cutting bit for CNC routers and conventional routers. This is the bit that adds elegance to your woodworking CNC project that gives it the extra character to make it stand out. The radius bit will round the borders or letters. It doesn't matter, as long as you have 1/4" to play with on your project, this 1/4 round cutter will spice your project up.

Only used it once since I received it two weeks ago but have been really impressed with it. Good finish and really changes the look of the job by not having all square edges or having to go to the router table after taking off the cnc

The IDC Woodcraft brand 1/4 Round Over Router Bit (a.k.a. rounding bit, radius bit) simplifies the toolpath setup. It is designed to come to a point, instead of having a flat at the bottom. This completely eliminates form-tool setup in your CNC design software. NO OFFSETTING OF THE 1/4 ROUNDING BIT IS REQUIRED!! Just set it up to run on a profile line at 0.245" deep and you end up with a perfect radius that requires minimal smoothing.
