⚡ At a Glance
- • Boring Accuracy: Micrometer lead screw provides 0.0001 direct reading accuracy and graduations of 0.001/0-50, head size 2.
- • Best for: Precision internal boring in small workshops and hobby machining environments.
- • Not ideal for: Heavy industrial boring tasks that exceed the size-2 head range.
Micrometer-equipped boring head designed for fine, repeatable adjustments. Graduations and direct-reading micrometer ensure controlled incremental changes.
Repeatable Precision – thanks to micrometer lead screw
A micrometer lead screw gives direct reading accuracy to 0.0001, with graduations listed as 0.001/0-50 for fine incremental control. The mechanism lets operators make small, measurable changes without recalibrating between cuts.
Repeatable bore diameters are achievable, reducing setup time when matching or replicating holes. Accurate adjustments help maintain consistent tolerances across multiple parts.
Flexible Boring Range – with multiple 1/2-inch carbide bars
The package includes nine 1/2-inch carbide boring bars designed to be fitted into the boring head's hole. Bars can be swapped to suit different bore sizes while maintaining the same head alignment.
Switching between bore diameters is faster, cutting down on downtime during small-batch work. Carbide bars offer wear resistance for longer service life under normal workshop conditions.
Straightforward Mill Mounting – with included R8 shank
An R8 shank is supplied to mount the boring head on compatible spindles, and the set includes necessary mounting hardware. Thread specification and component spacing support a secure assembly.
Quick mounting into an R8-equipped spindle gets machines back to work sooner. Secure clamping reduces chatter risk for cleaner bores and steadier feeds.
✨ The 4 Key Reasons for ALL-CARB Boring Head Set
- Nine 1/2-inch carbide bars — cover a wide range of bore diameters quickly
- R8 shank included — mounts directly into R8 toolholders for stable operation
- Maximum offset 5/8 inch — allows larger bore adjustments without changing head set-up
- Three Allen wrenches and mounting parts — ready to fit and adjust straight from the case
