Small-Bore Precision Boring—No Chatter, No Compromise
The OSCARBIDE 3/8"×6" SCLCR right-hand boring bar is engineered specifically for small lathes and small-bore finishing work. At 3/8" diameter, it strikes the perfect balance between rigidity and compatibility with compact tool posts—it fits, it cuts, and it delivers a finish you can be proud of.
What you get in your shop:
Mirror finishes in small bores – Minimum bore diameter 0.5" (approx. 12.7mm). The 80° diamond CCMT21.51 insert with R0.4 nose radius delivers Ra0.8–1.6 in steel and stainless—no more sanding internal bores by hand
Rigid enough, without overloading your machine – 3/8" shank drops right into standard mini-lathe tool posts—no sleeves, no modifications, no adapters needed
Coated inserts that keep cutting – CVD multi-layer coating (Al2O3+TiCN) acts like a heat shield for the cutting edge—significantly longer tool life than uncoated carbide when machining steel and stainless

Compatible Lathes
Q1: Will this boring bar fit my lathe?
A: Yes – if your lathe tool post or boring bar holder accepts 3/8′′ straight shank tooling . This fits most:
Mini lathes (7x, 8x, 9x series) – Sieg C2/C3, Grizzly G8688, Harbor Freight, Precision Matthews
Benchtop lathes – most 10′′-14′′ swing lathes with 3/8′′ tool capacity
CNC lathes – standard 3/8′′ boring bar holders
Quick-change tool posts (QCTP) – with 3/8′′ tool holder blocks
Critical : This bar requires a minimum bore diameter of 0.48′′ (12.2mm) . It will not fit holes smaller than this.
Q2: What lubricant should I use?
A: Use appropriate cutting fluid or coolant for your material. This is essential for:
Reducing heat and friction
Extending insert life
Improving surface finish
Preventing chip welding (especially on aluminum and stainless steel)
Q3: How do I install the inserts?
A: Use the included T-7 Torx key to:
Loosen the screw clamp (MTS-255 screw)
Rotate to a fresh edge or replace the insert
Re-tighten – do not over-torque
The screw-clamp design provides secure insert retention
Q4: How do I know when to rotate the insert?
A: Signs it‘s time to rotate:
Increased cutting resistance
Rough surface finish on the bore
Visible wear or chipping on the cutting edge
Unusual noise or vibration
Burn marks on the workpiece
Q5: Where can I buy replacement inserts?
A: Replacement CCMT21.51 (CCMT060204) inserts are available separately from OSCARBIDE and other suppliers. They are a standard, widely available insert type.
Q6: 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.
