Full-Size Ergonomic Carbide Turning Tool, Square Radius

Comfortable handle with rubber overmold for excellent control and reduced fatigue—replaceable square radius carbide tip needs no sharpening.
Item #
96% of 100

Take a close look at the edge of this carbide cutter and you'll realize it's not actually square. Instead, each of its four edges is slightly crowned with a 2'' radius. This subtle change makes the cutter excellent for smoothing cuts. The replaceable, rotatable cutter eliminates the hassle and downtime of sharpening. Simply rotate the carbide cutter for a fresh, sharp edge, and replace it once all edges have grown dull. Solid carbide stays sharp for longer when compared with steel, giving you a much longer useful life. The shaft features a flattened back for stability when using the tool rest, and the handles are made of solid ash encased with a thick, molded rubber end for an enhanced grip and reduced fatigue. They're great for beginning to advanced woodturners, ensuring quick success without the frustration of dull tools. Since you don't need to invest hundreds of dollars into sharpening equipment, they're also an excellent value.


  • Excellent for smoothing cuts and convex surfaces
  • Total overall length of approximately 19-1/2'' provides the leverage needed for heavy work
  • No sharpening needed, thanks to the replaceable, rotatable carbide cutter
  • Ash handles are coated with a soft, grippy rubber for a secure, effortless grip and excellent ergonomics

Full size TC turning tools
I had these in a smaller size ( three piece set) that I used mostly for pen turning. I needed something larger for bowl turning. They turn great, however check that the insert screws are tight. One came loose and I checked all three and they all needed tightening. I think I also had this problem with the smaller 3 piece set.

Great tools
Just learning how to turn wood. Started with cheap set of traditional tools and I just couldn't keep them sharp. Wish I had just started with these, much easier to use effectively. I bought all four tools (square, square with rounded edge, round, and diamond). I'm addicted.

Did quite a bit of research on turning tools and found that these were mentioned a lot with very good reviews. Plus, if Rockler has them, they must be a quality product.

Max G on Feb 23, 2019
smaller than most full-size, but bigger and sturdier than mid-size. Radius head is a plus without having to buy separately like many products. Great price

Struggling keeping HSS tools sharp. Hard wood eats them up. I have to stop and sharpen multiple times on a single project to keep clean cuts. Hope these solve that problem, reasonable price on sale.
Edwin M on Jan 19, 2019

Melissa J on Jan 5, 2019
Acrylics and other materiels need carbide tools or the HSS will dull quickly. These were priced right and the value is good.

I like the middle size tools I bought on sale to check out carbide tools. I thought there would be an advantage and some increased flexibility with the rounded corner..

Hi everybody! what is the principal difference between the Square Carbide and Square-Radius Carbide? i want to buy a round carbide and another one for rough cuts, which one you suggest?
Angelo C on Jan 31, 2017

Full-Size Ergonomic Carbide Turning Tool, Square
BEST ANSWER: I have the complete set of 4 different tips. I use the square for roughing but aso the square round for roughing smaller diameter items on the lathe. The round tool is a good clean up and smoothing around contours. The Diamond tip is food for shaping. I would probably purchase the square round for starter.
what size radii can you buy for this product?
Dr Dave on Aug 28, 2015
BEST ANSWER: We just have the one that comes with it, there are no other sizes, sorry
Can I use the square tool with the square radius tip (replacement cutter)?
Stephen H on Jan 24, 2018
BEST ANSWER: I have never tried to replace a square with the square radius tip. However, I do not see any reason this is not possible given the design of the handle itself. These are great tools for sure
I’m new to wood turning and just got a midi lathe. I want to turn chair/stool legs and small 1/2 dowels for my wood box hinges. Can someone recommend which carbide tools to start with ? Full size or mini. Txs
Carlos C on Jan 15, 2018
BEST ANSWER: I suggest you look at what you're planning. For the most part you may not need large tools and I would suggest intermediate size and go to larger tools in the future as you make larger projects.
Where are these made?
Kim P on Jan 8, 2016
BEST ANSWER: The labels that came with my tools state MADE IN TAIWAN
How long is this tool?
John C on Dec 12, 2018
BEST ANSWER: Overall length is 19 1/2" and the metal shaft is 6 1/2"
can I use the tool when making pens?
Gary A on Jan 29, 2017
BEST ANSWER: Yes, but you will be better off with a smaller tool. I use the full size tools for rough cuts and the smaller tools for final and finishing cuts.
Does both the square and square radius fit same handle ?
Jerry on Jun 23, 2019
BEST ANSWER: Hi jerry,
I have the square radius tool and just tried to put a square carbide tip in it and it fit but i have not tried to use it that way. I am not sure if the square radius carbide will fit in the in the square tool.
Hope that helps
P.S i love the tools. I have started trying to learn how to use conventional tools and find my self using the carbide tools to fix my mistakes.
What’s the best tool in this range for hollowing out?
