One Pass, Mirror Finish—No Luck Required

What this means for you:

Finish quality in one pass – R0.4 nose radius delivers Ra0.8 or better at 0.12mm/r feed—skip the secondary polishing

Hole-to-hole consistency – With emulsion coolant and steady feed, hold diameter tolerances within ±0.005mm

Change inserts without removing the bar – Dull edge? Loosen, rotate, tighten in under 30 seconds—no tool offset resetting needed

Stop Leaving Bore Quality to Chance—Open, Mount, and Deliver

The OSCARBIDE 3/4"×10" Indexable Boring Bar Set is built for machinists who demand internal bore accuracy and finish quality. 10 precision-finishing inserts, negative rake for stable cutting, chip breaker for chip control, and R0.4 nose radius for mirror finishes in one pass.

Compatible Lathes

Q1: Will this boring bar fit my lathe? A: Yes – if your lathe tool post or boring bar holder accepts 3/4′′ straight shank tooling -. This fits most large engine lathes, CNC lathes, and boring mills. The bar requires a minimum bore diameter of approximately 0.920′′ (23.4mm) .

Q2: What are the exact dimensions? A: Shank diameter: 3/4′′ (19.05mm). Overall length: 10′′. Minimum bore: approximately 0.920′′ (23.4mm). Right-hand SCLCR design.

Q3: How many inserts are included? A: The set includes 10 CCMT09T304 (CCMT32.5) carbide inserts -2. Each insert has 2 indexable edges – giving you 20 total cutting edges to start-2. Replacement inserts are available separately.

Q4: What does CCMT09T304 / CCMT32.5 mean? A: These are industry-standard designations for the 80° diamond insert shape :

CCMT : Clamp-style, 7° clearance, tolerance class M, chipbreaker style T

09T304 / 32.5 : Size specifications – 5/32′′ thickness, 11/64′′ hole diameter, 1/64′′ nose radius

Q5: What is the insert made of? A: The inserts are made of solid carbide with a multilayer coating , offering long tool life, faster cutting speeds, low friction coefficient, and good wear resistance. They are also TiN-coated for durability and moisture/rust resistance.

Q6: Can I use this bar on a manual lathe? A: Yes – this bar is designed for use on both manual and CNC lathes, as well as boring machines . The 3/4′′ shank fits most standard tool posts.

Q7: What materials can I machine? A: Mild steel, carbon steel, stainless steel (with proper speeds/feeds), cast iron, aluminum, brass, copper, and alloy steels-. Not for wood or abrasive composites.

Q8: Does this bar have through-coolant capability? A: No – this bar does not feature through-coolant. Use external coolant or cutting fluid applied to the cutting zone.

Q9: How do I change the inserts? A: Use the included T-15 Torx key to loosen the M4x8 screw clamp, rotate or replace the insert, and re-tighten-. Do not over-torque.

Q10: How long do the inserts last? A: Life depends on material, speeds, feeds, and coolant use – typically dozens to hundreds of parts per edge in mild steel. With 10 inserts × 2 edges = 20 fresh edges, you‘re set for a long time.

Q11: Where can I buy replacement inserts? A: Replacement CCMT09T304 (CCMT32.5) inserts are available separately from OSCARBIDE and other suppliers.

Q12: My bore is rough or oversized – what could be wrong? A: Check: insufficient cutting fluid, incorrect speeds/feeds, loose insert, or excessive depth of cut. Also ensure the bar is properly centered and the workpiece is securely held.
