E08K-SCLCR-2 Boring Bar Drawing

A 1/2" mini boring bar for CCMT 21.5 inserts, right hand, with a 95° lead angle. The carbide shank is about three times stiffer than steel, and the larger shank adds reach over the 3/8" bars: the same insert, deeper holes, a clean bore at stick-outs where a steel 1/2" bar starts to chatter.

Dimensions

Shank diameter: 0.500" (12.7 mm), with a ground clamping flat
Overall length: 5.000" (127 mm)
Head length: 1.500" (38.1 mm)
Minimum bore: 0.512" (13 mm)
Lead angle: 95°, right hand
Insert: CCMT 21.5, CCGT of the same size also fits
Coolant: external
Included: Torx clamping screw. T-8 key not included.

Inserts for this bar

Any CCMT 21.5 insert fits the seat, whatever the corner radius. A larger radius gives a stronger edge but pushes the bar harder sideways, so the longer the stick-out, the smaller the radius should be.

CCMT 21.50, HW2 finish, for steel — 0.008" radius, the lightest cut. The first choice for a finishing pass near full reach.
CCMT 21.51, HE3 semi-finish, for steel — 0.016" radius, general boring.
CCMT 21.51, HW2 finish, for stainless steel — 0.016" radius.
CCMT 21.52, HE3 semi-finish, for steel — 0.031" radius, the strongest edge, for roughing at a moderate stick-out.

For aluminum, a ground CCGT insert with a sharp edge cuts with less force than any CCMT.

How far it reaches

Keep the stick-out within about six times the shank diameter — roughly 3" — for a clean bore. For holes between 0.433" and 0.512", the 3/8" bar for the same insert is the one that fits. For bores of 0.945" and up that need more than 3" of reach, an anti-vibration boring bar cuts at 10 times its diameter.

Clamping

The bar mounts in a boring bar holder on the turret, or in a holder with a larger bore through a split sleeve. Set the clamping screw on the ground flat: it fixes the rotation of the bar and keeps the cutting edge on center height.
