Gundrills

Single-flute gundrills for high-precision deep holes — available under GMG Private Label.

Precision gundrills for deep, accurate holes

Gundrills use a single flute and high-pressure through-coolant to drill holes with a high depth-to-diameter ratio while holding exceptional straightness and surface finish. They’re the tool of choice when a hole is far deeper than it is wide and quality can’t be compromised.

GMG Solutions supplies gundrills under our GMG Private Label — specified for your diameter, depth and material, and backed by our on-machine engineering support.

Key points

High depth-to-diameter ratios with excellent straightness
Fine surface finish, often removing a secondary operation
Resharpenable — pair with our resharpening machines for in-house maintenance
Specified and imported to order for your exact application
