Title: Carbide Tipped Tool Bits need some help
Post by: Ye-Ole Steam Dude on November 08, 2018, 04:45:52 PM: Hello everyone,

I cannot find any source here in the US for style CT (cutoff / parting ) Carbide Tipped Tool Bits in grade C2 and C6 in a size ½" x ½". I have found some in size ½" x 1" high which will not fit in my quick change tool post. I would also take the style ISO7R.

If anybody has a source please let me know.

Have a great day,
Thomas

Brazed carbide tipped blades, or indexable carbide tips? Do you need the blade/bit holder also, or just the carbide blade/inserts?

I don't know what carbide is on the brazed blade, it doesn't specify. I'd assume you could find whatever carbide tips you want for the indexable cutter blades. LMS carries C6 and C2 carbides to fit their indexable holder blade.

Hello Bent,

No the Carbide Tipped are the one that are brazed on tips.

Have a great day,

Hello again Bent,

What I am looking for is a one-piece tool after the tip has been brazed on. No replacement inserts or the indexable style.

The Cutoff/Parting tool come in "sets" and in the past could be purchased individually like the other tools. I found one company in the US that offers the 1/2 x 1/2 size but they sell for $18.95 plus shipping at $6.25 each. Normally an individual tool (C2 or C6 grade) sells for $4 to $8.

Thanks for your help,
Thomas

I gave in and placed an order with Banggood for some Bits, now I will find out if they have quality products. If any body does have a US source for these bits please let me know.

Have a great day,
Thomas

Just a follow up on the lathe tool bits. I could not find a local (USA) source for a (style “C”) Carbide Tipped cutoff bit that was ½" x ½" shank so I placed an order with Banggood for a DIN equivalent. Shown in the photo is a DIN 4981 which is 12mm x 8mm (.475" x .317') shank. The tip is .140" wide at the widest point, this I like because it is a bit narrower. The max cutting depth (close estimate) is .525 which is also good.

I have only used one tool so far to make two cuts in some 3/4" 1018 steel round rod but it cut real good with no problems. Not enough usage at this time to give an opinion of the quality but I am glad to now have eight of these in my tool cabinet and three 10mm x 10mm that I ordered at the same time.

It did take a long time to receive them after placing the order, about 26 days, but I was not in any rush. I did pay for them with PayPal.

Have a great day,
Thomas

Hello Doc,

I had been on their website before but could only find 1/2" wide by 1" high bits and my quick change tool post will not handle above 5/8" high bits. Almost all of my bits are 1/2x1/2 with a few in 3/8" size. I'm not sure but the link you show has the 1" high bits.

It's funny that the "C-style" in 1/2x1/2, in both grade 2 and 6, are available in the "kits" but not as individual pieces. :headscratch:

Thanks for you help and have a great day,
Thomas

Hey again Doc,

I have the quick change holder for that style of blade but have never used it. Guess I should go ahead and order couple of the blades in different thicknesses.

Thanks Doc for you help and have a great day,
Thomas
