Reduced Exit-Hole Chipping
The thru-hole geometry is intended to minimize chipping as the drill exits laminate, particle board, MDF, and solid wood.


Carbide-tipped left-hand thru-hole drill engineered for clean exit-hole performance in laminate, particle board, MDF, and solid wood. The verified D150.150L configuration combines a 15 mm cutting diameter, 40 mm cutting edge, 10×20 mm shank, and 70 mm overall length for CNC drill banks and compatible portable machines.
Industrial-quality carbide-tipped thru-hole drill with a larger carbide tip and improved geometry for production drilling. The design is intended to minimize chipping as the tool exits laminated and wood-based panels.
Designed for CNC drill banks and compatible portable machines using the verified 10×20 mm shank interface. A screw in the end of the tool provides height adjustment.
The Royce Ayr D150.150L is an Industrial Quality Thru-Hole Drill for production drilling where clean exit-hole quality matters. The exact verified configuration is a 15 mm cutting diameter, 40 mm cutting edge, 10×20 mm shank, 70 mm overall length, and left-hand rotation.
Royce Ayr specifies the industrial thru-hole family for CNC drill banks and portable machines. Its carbide-tipped cutting edges, larger carbide tip, and improved geometry are intended for long service life while helping minimize exit-hole chipping in laminate, particle board, MDF, and solid wood.
A screw in the end of the drill provides height adjustment for controlled setup. Confirm that the spindle accepts the exact 10×20 mm shank and requires left-hand rotation, then verify tool seating, adjustment, runout, drilling depth, breakthrough clearance, feed rate, RPM, extraction, and workpiece support before production.
