Sources for carbide bits? and stock?

[Haynie]

If I choose the carbide tools where do you get the wood cutting carbide bits from? My initial thought was they were not any different than what is used for metal but I have since been set straight on that thought.

What are the shafts of the carbide tools made from? Are they just square bar stainless steel?

Mark -- just as there are different carbide inserts for different metals and machining operations there are also a few different approaches to hand held carbide insert tools.

Two general groups --

Cup style insert tools such as those by brand names of Hunter and Eliminator

Flat top insert tools such as those sold by Ken and George (here on IAP) and by such as EZ Tools. These includes round, square, diamond, and squarish with long radius edges.

Stainess Bar works - as will other bars and shapes -- you should have a filed/milled flat, a good support for the bottom, protection for the back edge, and the hole threaded to match the insert and screw that mates to it.

You might want to borrow and use a few if you can -- or buy one to see the tolerances for mounting the insert.

Take some care in making sure the insert is well supported-- shattered carbide shards can do bad things.

So where to get the replacement bits? I was not planning to make the tools myself yet but am always prepared with extras in case I flub up or drop something and it breaks. If I have an extra bit in the wings I won't cuss so much.

 

[KenV]

Mark -- those who sell the tools also sell replacement inserts -- and screws that fit the inserts. You want both for replacement in case you drop the screw into the chips.

Pick a style and vendor -- The Pen Pro by Ken Ferrell (Bitshird) here on IAP is a good starting point. Ken has good support and will sell the replacement inserts for a reasonable price.

I might get flamed by a few that sell these tools, but im going to let you and anyone else who reads this and uses the larger style inserts know where the best place to buy your inserts is.

No Flame on my part -- just the observation that I have tried some of the planer inserts (but not from that firm) and found that they were priced about right for the effectiveness and useful function in lathe work. I expect they are very good with lots of horsepower and speed at shearing off bites of planks in a planer. The edges are designed for a lot of impact and a different presentation angle than I use on a lathe.

Try them and compare with the ones mounted on tools for lathe work and make up your own decisions.

Have been for about 6 months now in my Woodchuck Penpro(which by the way is the ONLY turning tool i use from start to finish, even on my kitless pens)and they are as good as any i bought with the tool. Some may disargee but i have gotten the same long use from these as the others. I can rough a blank in a few minutes with these and go straight to 600 grit. I cant remember the last time i used any sandpaper less than 600 grit after using these blades on this tool.

Just my observations:biggrin:

I picked up my bars & inserts @ http://eddiecastelin.com/products_and_services

I've got no complaints.

Im sure those are great and i know the Capn Ed is a great guy. But the difference here is the price of the inserts. $6 rather than $2.35 a piece. Thats a huge difference.

On a square insert , Yes. For a round I only see 11 mm @ $9.00 and I see no diamond shape either. I normally only use my 12mm round cutter. I've only used the square a few times. I might try this place for those but will be a long time before I dull out the square insert.

Yep your right. I dont use the rounds or diamonds nor do i have a tool to use them in. Im not doing bowls or coves and things. I cut strait flat shoulders to cut threads on and rough out acrylic and shape it for sanding. Im sure that most on here are just using the radius face and a few the straight face, so this really pertains to them and not to anyone using round or diamond inserts. Those i have no idea about.

There is a member on here.I think he goes by wood-of-1-kind and he sells both the ROTONDO which is rounded and the SKOGGER which is square.He also sells the replacement tips for both. I switched to his Rotondo a couple years ago and now I use it for 99% of all my turning.Even aluminum.I love the tool.
