370 BORING • Heads & Shanks UNIVERSAL BORING & FACING HEADS IbonrcilnugdetsooFlRs,EsEleTeovoelsi,ngextpeacnksaigoensco&mplfeittetewd ictahseboring bits, BENEFITS: • Automatic slide feed makes possible facing, back-facing, and taper machining. • Allows for multi-tool boring. • Advantage over manually adjusted boring heads such that auto-feed can be automatically set to advance the boring tool laterally. • Automatic Boring Heads are preferred to improve the surface finish of the wall. ♦ S hanks Not Included In Sets. APPLICATIONS: • Ideal for boring in a wide range of diameters. • Suitable for precision boring of cylindrical holes and for machining of external cylindrical surfaces. • Turning internal and external surfaces by summing up the spindle feed with an automatic feed of the head. • Also used for facing, Internal recessing, recessing, back facing, boring of taper hole, machining of external taper, and thread cutting. FEATURES: • Adjustable slide feeds in three or four grades. • Guaranteed fast setting with ±.0002" accuracy. • Heads can be safely rotated in either direction. • Interchangeable shanks with short taper and flange connection for accuracy, power, and rigidity. However, Shanks is not included in the set. • Available shank description: R8, 30/40/50 ISA Shanks & 2/4/5/6 Morse Taper Shanks. • Lubrication is distributed from two points to all friction surfaces. • Quality construction throughout with all parts hardened and precision ground for long life and extreme accuracy. • Sturdy fitted case. • Boring bars use CCMT 21.51 and TCMT 21.51 inserts.
