SGS Tool Co. says the key features designed into the SGS Hi-PerCarb drill allow the product to offer application benefits not only beyond that of standard carbide drills, but also other high-performance drills. Each feature of the SGS Hi-PerCarb drill was uniquely engineered as a solution toward addressing the issues commonly encountered during high production drilling.
The stability of the double-margin design and penetration capability of the point geometry allow the Hi-PerCarb drill to address demanding applications that would normally require reduced operating parameters or a two-step process.
The second margin gives the Hi-PerCarb drill a burnishing effect and the flute form effectively controls and transports chips, allowing the drill to offer superior surface finishes and hole size in high production environments, saving cycle time by often avoiding the need for reaming in many applications.
The secondary flute provides a channel for cooling capabilities normally not found in external coolant drills. This, combined with the Ti-NAMITE A tool coating and the high-strength edge design results in increased operating parameters with additional tool life.

Finishing method by means of compressing or cold-working the workpiece surface with carbide rollers called burnishing rolls or burnishers.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
