Main Product Description
The Royce Ayr D100.111L is a left-hand industrial woodworking drilling tool engineered for accurate production boring. Its verified 7/16 in diameter and 57 mm overall length are carried directly from the product identity.
The exact catalog identity verifies 7/16 in diameter, 57 mm overall length, left-hand rotation and brad-point geometry. Royce Ayr publishes D100 as an industrial carbide dowel-drill family using the 10 × 20 mm platform, but this exact special size is not listed in the current standard dimensional table. No unsupported CE, b1 or Z value is added.
Before production, confirm left-hand rotation, toolholder compatibility, insertion depth, runout, drilling depth, secure workpiece support, and suitable spindle/feed parameters for the material being machined.
