Complete 12 piece set. Includes: 1/8" thru 3/4" in 1/16" increments plus 7/8". R-8 COLLET SET - 12 PIECE. Review: great deal for the cost - I am not a full time machinist. The collets work great for what I need them for. The price was good and I am sure that they will last me a long time since most of their life will be spent in a drawer. Review: Very consistent with an average run-out of .0002" on the 8 out of 12 holders I have dial tested - Got these as a brand new set that came with my PM-45M CNC. The person I purchased the machine from also included a set of 20+ Tormach ER20 tool holders & Tormach R8 to Tormach tooling adapter(just an R8 collet). When comparing the the run-out using the Grizzly R8 collets vs the Tormach Tool holders on a .0001" gradient dial test indicator I am seeing an average of .0002" and a max of .0004" run-out at the end mills shank using the Grizzly collets. With the Tormach holders no matter what I do simply loosening them and re-tightening the holders can cause up to .0018" of run-out to occur when the previous mounting seconds before showed less than .0007". I have tried using the grizzly R8 collet with the Tormach holders, clocking the ER20 collets and even going to high end collets/end mills but always the Tormach tooling system just does not like to mount consistently in the R8 tooling. Maybe this would change with a powered drawbar vs a bolt/nut style but either way I'm surprised the Tormachs come as highly recommended as they do and the Grizzly's are considered poor quality by comparison. IMO .0002" average run-out is amazing for the price and I am now considering selling the Tormach holders or going to a BT30 spindle & powered drawbar. NOTE: The attached photo shows less than .0001" run-out at the end mill. I have zero set @ #2 for clear indication of negative and positive. ## Features - Made from the highest-grade steel available for collet manufacture these collets are precision ground to very close tolerances - Complete 12 piece set - Includes: 1/8-Inch thru 3/4-Inch in 1/16-Inch increments plus 7/8-Inch ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0000DD0OL | | Best Sellers Rank | #2,258,394 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2,551 in Router Collets | | Brand | Grizzly Industrial | | Brand Name | Grizzly Industrial | | Capacity | 0.75 inches | | Compatible Devices | Lathe, Milling Machine | | Customer Reviews | 5.0 out of 5 stars 5 Reviews | | Handle Type | wrench-tightened | | Included Components | 12 Pc.
