H- (Coolant Feature): Indicates that the boring bar has an internal through-coolant hole system. This blasts high-pressure coolant directly at the cutting edge to push chips out of deep, tight internal face cavities.
TTIL (Series & Direction): Represents a TaeguTec Internal Left-Hand (L) face grooving tool line using their signature T-Clamp system.
16 (Shank Diameter): The round mounting bar features a 16 mm outer diameter.
3C (Insert Clamping Width): The pocket seat is machined to tightly secure 3.0 mm wide indexable grooving inserts (such as standard TaeguTec TDC 3, TDJ 3, or TDT 3 series).
16 (Minimum Entry Bore / Diameter): Indicates that the minimum tool clearance allows it to safely enter a pre-drilled bore diameter starting around 16 mm without rubbing.
Matching Machine Tooling
Because this bar has a 16 mm round shank, it can be mounted directly into a large CNC turret station by sliding it straight into your previously discussed CNC Turret Sleeve Q50 16MMX100L to achieve perfect rigidity.
