ZD25-4-10D-330Made to order

1.000" diameter steel body with an internal damper, 12.992" overall length, 10xD of reach. The damper absorbs the chatter that limits a plain bar, so the tool holds size at overhangs where a solid bar cannot cut. Through-coolant to the head. The cutting head is ordered separately and sets the minimum bore and the insert.

ZD25-4-10D-330 Anti-Vibration Boring Bar Drawing

Anti-vibration boring bar body for deep internal turning, 1" diameter. Alloy steel body with 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. As an inch bar it clamps straight into a standard 1" boring bar holder — no sleeve, no metric bore. Bores from 1.181" (30 mm), up to 9.843" (250 mm) deep.

Dimensions

D1 — bar diameter: 1.000" (25.4 mm)
L — overall length: 12.992" (330 mm)
L1 — reach with the head fitted: 9.843" (250 mm), 10xD. The 230 mm (9.055") on the drawing is measured to the bar face, without the head.
Clamping length: 3.937" (100 mm) of the body stays in the holder at full reach
Head coupling: 25 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. Three 25 mm boring heads fit:

CCMT 32.5 head, 95° — boring and facing the bottom of a bore, from 1.181" (30 mm).
DCMT 32.5 head, 93° — light cuts, finishing and profiling, from 1.181" (30 mm).
DCMT 21.5 back boring head, 93° — cuts on the pull-out stroke, to face the back of a shoulder or bore behind a narrower entry, from 1.260" (32 mm).

The heads take standard CCMT and DCMT turning inserts.

Which bar for which bore

For bores between 0.945" and 1.181", the 20 mm anti-vibration bar is the one that fits. From 1.575" (40 mm) up, the 32 mm bar is stiffer and reaches 12.6" deep, and from 2.362" (60 mm) the 2" bars take over. In the 1.181"–1.575" range this 1" bar is the tool for bores close to 10" deep.

Clamping

Clamp the bar in a 1" boring bar holder with the full clamping length inside. The damper is tuned for 10xD, so the bar does its best work between about 7xD and full reach rather than choked up short.
