Drill Sleeve Reducer R8 to Morse Tapers (Metal, R8 (OUTSIDE) TO MT3 (INSIDE))

These are made of tool steel grade 8620 instead of mild steel, which is a much better quality of tool steel in terms of strength, finish, performance and hardness. Our drill sleeves are of A grade where the Inside tapers are also precisely ground (*not blue matched tapers like other cheaper suppliers to reduce the cost) High precision quality of under 5 microns run out. Hardened & precisely ground. Drawbar thread is 7/16" UNF for Bridgeport & same other drawbar milling machines Available in R8 to 3MT & R8 to 2MT options, pls chose from our drop down as per your needs. thanks
