Increased tool liferesults in longer periods of unmanned machining. The machining speeds for Crystallume DCC tools can be increased 2 to 3 times over the speeds used with carbide tools to increase your productivity. These features combine to increase the utilization of your machine tools. Crystallume's Mold Maker and Extended Shank tools offer features specifically for electrode and mold manufacturing. The Mold Maker tools have a 5 times diameter flute length with an extended shank. The big difference is the tolerance of the tools. With a cutting diameter up to 1/8" and 3mm the tolerance is +0.0000/-0.0005 and for tools larger than this, the tolerance is +0.0000/-0.0010. All shanks are held to a tolerance of -0.0001/-0.0003 to assure consistent and concentric gripping in shrink-fit holders. Mold Maker tools are available in sizes from 1/64" to 1/2" and from .5mm to 6mm in diameter. Tools below 1/4" and 6mm are available with and without extended reach. Crystallume Mold Maker tools are the most precise diamond coated tools available. The Extended Shank tools combine a short-flute length for maximum rigidity with a long shank for extended reach into deep cavities. When the extended reach is not required, you can choke up on the tool to make it extremely rigid as a stub tool. This is a great all-around tool that will become a workhorse in your shop. 2 Flute Mold Maker End Mills (With Reach) Cutting Diameter Flute Length Overall Length Reach Length End Style Shank Diameter

As a reference, it is usually 18 to 20 microns on 1/4" diameter and larger tools. (This coating is available on all products, end mills, drills, inserts and as a toll coating, it's our best general-purpose coating.)

Crystallume DCC tools are finding rapid acceptance among manufacturers of graphite electrodes for use in EDM operations because they last 10 to 30 times as long as carbide tools currently used. Increased tool liferesults in longer periods of unmanned machining. The machining speeds for Crystallume DCC tools can be increased 2 to 3 times over the speeds used with carbide tools to increase your productivity. These features combine to increase the utilization of your machine tools. Crystallume's Mold Maker and Extended Shank tools offer features specifically for electrode and mold manufacturing. The Mold Maker tools have a 5 times diameter flute length with an extended shank. The big difference is the tolerance of the tools. With a cutting diameter up to 1/8" and 3mm the tolerance is +0.0000/-0.0005 and for tools larger than this, the tolerance is +0.0000/-0.0010. All shanks are held to a tolerance of -0.0001/-0.0003 to assure consistent and concentric gripping in shrink-fit holders. Mold Maker tools are available in sizes from 1/64" to 1/2" and from .5mm to 6mm in diameter. Tools below 1/4" and 6mm are available with and without extended reach. Crystallume Mold Maker tools are the most precise diamond coated tools available. The Extended Shank tools combine a short-flute length for maximum rigidity with a long shank for extended reach into deep cavities. When the extended reach is not required, you can choke up on the tool to make it extremely rigid as a stub tool. This is a great all-around tool that will become a workhorse in your shop.

Standard Premium is our original and the most versatile coating thickness. For reference, it is approximately 18 to 20 microns thick on 1/4″ and larger diameter tools. This is our best general purpose coatingand is available on all products – end mills, drills, inserts and as a toll coating.

If you are a beginner, we recommend our sister site, Common Woodworking, which takes you through how to make a dovetail step by step:

It’s not really a good habit to gang up dovetails. In many cases ganging them up together can result in both dovetails being out of square or misaligned or both and thereby the two dovetails end up being different sizes. Also, the very practice we need when we begin dovetailing is denied by introducing something we never really do in practice.

The Extended Shank tools combine a short flute length for maximum rigidity with a long shank for reaching into deep cavities. When the extended shank is not required, you can choke up on the tool to make it extremely rigid as a stub tool.

Paul Sellers & Company Ltd-Paul Sellers & Company Ltd is a company registered in England and Wales with the company number 10347569. The company's registered address is Accsol House High Street, Johnstown, Wrexham, LL14 2SH, United Kingdom.

We tend not to use the coping saw method for the majority of fine woodwork and furniture making, as it is not as precise and it takes quite a bit of practice to get as accurate as Paul is at it. There is also risk of tear-out. So for fine work we would use the method as seen in our making a dovetail video above. Paul might use a coping saw for rougher carpentry, but the cuts are consistently finer when done with the chisel.
