11/32 in Verified Diameter
The catalog identity and source data support the stated diameter, handedness and overall-length configuration for D150.087L.


Royce Ayr D150.087L is a 11/32 in left-hand carbide-tipped V-point thru-hole drill. Its verified 70 mm overall length and SKU-specific geometry support accurate production drilling in compatible woodworking systems.
Left Hand-hand V-point thru-hole drill with a verified 11/32 in diameter and 70 mm overall length in the D150 family.
For compatible CNC drilling and woodworking boring systems configured for left-hand tooling and the verified interface requirements of this SKU.
The Royce Ayr D150.087L is a left-hand V-point thru-hole drill engineered for industrial woodworking drilling. Its verified 11/32 in cutting diameter and 70 mm overall length support repeatable production boring.
Published or primary-source data for D150.087L confirms a 10 × 20 mm shank platform. This exact 11/32 in SKU is not present in the published standard D150 dimensional table used for this batch, so unsupported CE, b1 and flute-count values are intentionally not assigned.
Before production, confirm rotation, toolholder or adaptor compatibility, insertion depth, runout, drilling depth, workpiece support, and suitable spindle/feed parameters for the material being machined.
Technical Specifications
The catalog identity and source data support the stated diameter, handedness and overall-length configuration for D150.087L.
The SKU-specific family geometry is retained without importing unsupported dimensions from adjacent drill sizes.
D150.087L is configured for left-hand boring positions and should be installed only in the corresponding machine station or spindle direction.
Verify the exact SKU, rotation, drill-bank or adaptor interface, toolholding condition, insertion depth, runout, drilling depth, workpiece support, and machine parameters before production. This exact 11/32 in SKU is not present in the published standard D150 dimensional table used for this batch, so unsupported CE, b1 and flute-count values are intentionally not assigned.
Royce Ayr D150.087L combines a verified 11/32 in diameter, left-hand rotation and 70 mm overall length with the verified D150 family geometry stated above.
Correct tool selection, rotation, interface fit, setup, runout control, workpiece support, and machine parameters are essential to the intended drilling performance.
