YG-1 Stub Length Drill Index – 29 Piece, 1/16" to 1/2"

Drill a wide range of precision hole sizes on the MR-1 CNC Gantry Mill with this YG-1 29-piece Stub Length Drill Index.

Manufactured by YG-1, a recognized global cutting tool manufacturer, this set includes every fractional drill size from 1/16" through 1/2" in 1/64" increments, providing a versatile selection for CNC machining, fabrication, and general-purpose drilling.

Each drill is manufactured from M2 high-speed tool steel and coated to improve wear and corrosion resistance. The stub-length design provides increased rigidity and reduced overall tool length, helping minimize deflection while providing additional clearance when drilling taller workpieces on the MR-1.

A 135° drill point helps promote accurate starts and efficient cutting, making this set well suited for CNC machining applications.
