Boring Heads

These widely known ELMECA 202 & 203 Series Boring Heads are readily adapted on many machines. An important feature of these heads is the threaded back which can be fitted with interchangeable Shanks. All Elmeea boring heads have a clearly graduated lead screw of heat treated tool steel with threads ground from solid. AFTER HARDENING.

Since, space is usually an important factor, the overall length of These Boring Heads is held to minimum. This feature has the further advantage of contributing to greater tool rigidity which in turn assures a smoother, more accurately bored hole. The generous bearing surface of these heads makes possible heavy roughing cuts, and more accura finish cuts.

Another important feature is the large adjustment range. This often eliminates off set bars and special set ups. Since the graduation are widely spaced and easy to read, adjustments of 0.0005 and less are easily made. All parts subject to wear are hardened to guarantee long life and continued accuracy.
