GT-39 Tri Flute Drill
The GT-39 Tri-Flute Drill is a high-performance solid carbide tool engineered for precision drilling in advanced composite materials. Designed with three cutting edges and three lands, the GT-39 offers enhanced hole size control, superior surface finish, and excellent guiding stability – even under heavy feed rates. Its thicker web increases strength and durability, making it ideal for demanding drilling operations where precision and tool life are critical.
Whether used in manual or CNC machining, the GT-39 ensures reliable, clean results in carbon fibre, glass fibre, and reinforced polymers.
Key Benefits
- Tri-Flute Geometry: Improved hole size control and smoother surface finish.
