Bordo 2654-18.00 – Reduced Shank Drill 1/2″ 18mm

Bordo reduced shank HSS drills are ground and then a black finish is achieved by steam tempering, a thermal process resulting in a porous tool coating. This surface aids chip flow and heat dissipation. The drill is then ground a second time to achieve a bright finish on the shank and cutting edges.SpecificationsDiameter: 18mmShank Diameter: 1/2in (12.7mm)Flute Length: 89mmOverall Length: 152mmPoint: Notched 118Helix: 30
