Description
Product Overview
The Sandvik Coromant S16R-SCLCR06 is a 16mm bore, 200mm long internal turning bar designed for machining small bores with CCMT 06 series inserts. Built to Sandvik’s CoroTurn platform, this solid steel shank boring bar gives you the rigidity and reach needed for internal profiling, facing, and finish turning in bores down to approximately 20mm diameter. If you’re running a manual lathe or CNC turning centre and need a reliable, insert-indexable boring bar that takes readily available CCMT inserts, this is a practical, no-fuss solution.
- 16mm round shank, 200mm OAL — the 16mm shank seats squarely in a standard boring bar holder or tool post, while the 200mm length gives you enough reach for moderately deep bores without the flex penalty you’d cop from a longer unsupported overhang. Keeping overhang to 4× diameter or less will give you the cleanest finish and longest insert life.
- SCLCR insert pocket geometry — the SCLCR designation means the pocket accepts CCMT 06 series inserts at a 95° lead angle with right-hand cutting orientation. That geometry gives positive chip clearance and suits both roughing and finishing passes on steel, cast iron, and aluminium in a single tool setup.
- Solid steel shank construction — unlike brazed carbide or carbide-shank bars, the steel body is forgiving to set up and easy to true in the holder. The knurled grip section along the shank makes it easier to rotate and lock the bar without it walking when you’re tightening the clamping screws.
- Compatibility note — takes CCMT 06 02 or CCMT 06 04 inserts (CCMT060204 / CCMT060208 in ISO notation). The 14 included Tungaloy carbide inserts are CCMT 06 series and fit directly — you have cutting edges ready to go out of the box. Standard 16mm boring bar holders and turret tool blocks suit this shank without modification.
- Ideal for — finish boring and internal profiling on manual engine lathes and CNC turning centres; cleaning up drilled or rough-bored holes to size; single-point boring to a diameter in four-jaw chuck setups; light facing of internal shoulders; small-batch jobbing work where quick insert indexing matters.
Condition
(Used — Good Condition / Previously Run, Functionally Sound)
The boring bar shows clear evidence of workshop use — the shank has the expected patina, tooling marks from clamping screws, and general bench wear along the body consistent with regular lathe use. The insert pocket and clamping screw seat appear intact and undamaged; the seating face that the insert registers against is the critical surface here, and it shows no visible deformation or chipping that would compromise insert seating or repeatability. The shank is straight — no visible deflection or bending — which is the primary functional concern with a boring bar of this length. Clamping screw threads appear serviceable. The 14 Tungaloy CCMT 06 carbide inserts included are new, still seated in their original plastic tray, and represent genuine usable value. A used boring bar in this condition is entirely fit for purpose; the insert pocket geometry and shank dimensions are what define the tool’s accuracy, not the cosmetic finish on the body. If you’re particular, seat a fresh insert, take a light trial cut, and measure your bore — that’s the real verification.
Included:
- 1 × Sandvik Coromant S16R-SCLCR06 boring bar (16mm shank, 200mm OAL)
- 14 × Tungaloy CCMT 06 series carbide inserts (new, in tray)
Not included: clamping screw / torx key (Sandvik Torx T8 or T9 typically required — confirm against your existing tooling), boring bar holder, coolant fittings.
Brand Information
Sandvik Coromant is a Swedish cutting tool manufacturer and a division of the Sandvik Group, widely regarded as one of the top two or three insert tooling brands globally — sitting alongside Kennametal and Iscar at the premium end of the market. Their CoroTurn platform, of which this boring bar is a part, set the industry benchmark for indexable insert tooling geometry and is the reference standard in most modern toolrooms and CNC turning facilities worldwide. Sandvik tooling is specified by OEM machine shops and aerospace subcontractors precisely because the insert pocket tolerances and ground geometries are held tightly enough to deliver consistent results across index cycles.
