ER20 Collet
Description
I Wanted To Make A Collet Tray For My Er20 Collets, So I Drew These Collet Models To Help Me Do It. I Found That The Measurements And Standards Vary A Bit, So I Actually Came Up With 3 Different Models. The Inch Model Is Based On The Drawing I Found On The Maritool Website, The Metric Model Is Based On The Drawing I Found On Aliexpress, And The Measured Model Is Based On My Own Caliper Work With The Set Of Drillpro Collets That I Ordered From Banggood. All 3 Models Are Based On The Same 30Deg Nose And 8Deg Tail, Because That Specific Was The Same In Both Drawings (And I Don'T Have An Accurate Way To Measure That Myself). All Three Are Slightly Different, But The Collets That I Measured Appear To Be Closer To The 'Inch' Drawing'S Dimensions. Still, I Figured That I'D Include All 3 In Case You Have A Different Experience. My Collets From Banggood Also Seem To All Have A 10Mm Id On The Back Side, So That'S The Size Of The Through Hole That I Added To These Models. Your Mileage May Vary.
