T.M. Smith Tool has added Jacobs taper rigid ER collet chucks to its family of Jacobs taper tooling.

T.M. Smith Tool has added Jacobs taper rigid ER collet chucks to its family of Jacobs taper tooling. These durable collet chucks are manufactured from premium-grade, through-hardened steel. The ER collet pockets are precision-ground to provide total indicator runout of 0.0002" or better. The company says that these collet chucks provide better concentricity and holding power than keyed and keyless drill chucks. 

Available with a Jacobs taper #1, #2, #33 and #4 (JIFFY), these holders are primarily used in drilling applications. They are compatible with standard Jacobs taper spindles and accept standard ER collets. The chucks are available in ER16, ER20 and ER32 versions. Specials are always available to meet customer-specific needs. ER collets are ordered separately.
