Technical Description

RD20-10D-260CR Anti-Vibration Boring Bar Drawing

Anti-vibration boring bar body for deep internal turning in small bores. Steel shank with a carbide-reinforced front section and a pre-tuned damper inside, set to this bar's own resonance, so it holds size and finish at reach where a plain bar chatters. At 20 mm it is the smallest anti-vibration bar in the range: bores from 0.945" (24 mm), up to 7.874" (200 mm) deep.

Dimensions

D1 — bar diameter: 20 mm (0.787")
L — overall length: 270 mm (10.630")
L1 — reach with the head fitted: 200 mm (7.874"), 10xD. The 184 mm (7.244") on the drawing is measured to the bar face, without the head.
Clamping length: 86 mm (3.386") of the body stays in the holder at full reach
Head coupling: 20 mm, two clamping screws
Coolant: through the body to the head

Boring heads for this bar

The head is ordered separately. It screws onto the front of the bar, carries the insert and sets the minimum bore of 0.945" (24 mm). Three 20 mm boring heads fit:

CCMT 32.5 head, 95°, right hand — boring and facing the bottom of a bore.
DCMT 32.5 head, 93°, right hand — light cuts, finishing and profiling.
DCMT 32.5 head, 93°, left hand — for a reversed spindle or a left-hand setup.

Both heads take standard CCMT 32.5 and DCMT 32.5 turning inserts, the same size as many OD tools use.

Which bar for which bore

Below 0.945" an anti-vibration bar does not fit, and a 1/2" solid carbide mini bar is the way to more reach. From 1.181" (30 mm) up, the 1" anti-vibration bar is stiffer and reaches 10" deep. Between the two, this 20 mm bar is the one tool that bores 7.874" deep without chatter.

Clamping

The bar clamps in a holder with a 20 mm bore, or in a larger holder through a split sleeve with a 20 mm bore. Keep the full clamping length in the holder: the damper is tuned for 10xD, and the bar works best between about 7xD and full reach rather than choked up short.
