From its advanced VDS point geometry designed to reduce chipping on the cutting edge to its precision shank engineered for low runout, the WIDIA VariDrill is a new multi-application drill engineered to deliver acceptable hole finish and extended tool life across a wide range of materials, including in steels, stainless steels, cast irons, non-ferrous materials, and high-temperature alloys. VariDrill features an advanced point geometry and "marginless" design that reduces chipping on the tool's edge and stabilizes cutting forces.
The VariDrill point and flute design enables chips to roll smoothly and evacuate easily, resulting in noticeably less friction, heat, jamming, and scratching. Minimizing these drilling issues means users can expect an optimal surface finish with every hole across a wide range of work materials without fear of catastrophic failure due to chip jamming. WIDIA VariDrill also offers the broadest portfolio of standard drill configurations available on the market. The VariDrill portfolio features 3XD, 5XD, and 8XD lengths, as well as coolant-through and solid options. The drills can be reconditioned, further extending tool life and adding tool value for general engineering users.
When asked what makes the new VariDrill such a revolutionary development for customers, Chris Merlin, Sr. Global Product Manager for Widia Holemaking products commented, "The new VariDrill is a game-changer in terms of drilling across multiple workpiece materials. With its huge range of standard line item configurations for easy ordering, and its unique design, it will become the go-to drill for shops facing quick-changing holemaking requirements."

- alloys
alloys
Substances having metallic properties and being composed of two or more chemical elements of which at least one is a metal.
- cast irons
cast irons
Cast ferrous alloys containing carbon in excess of solubility in austenite that exists in the alloy at the eutectic temperature. Cast irons include gray cast iron, white cast iron, malleable cast iron and ductile, or nodular, cast iron. The word “cast” is often left out.
- shank
shank
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
- stainless steels
stainless steels
Stainless steels possess high strength, heat resistance, excellent workability and erosion resistance. Four general classes have been developed to cover a range of mechanical and physical properties for particular applications. The four classes are: the austenitic types of the chromium-nickel-manganese 200 series and the chromium-nickel 300 series; the martensitic types of the chromium, hardenable 400 series; the chromium, nonhardenable 400-series ferritic types; and the precipitation-hardening type of chromium-nickel alloys with additional elements that are hardenable by solution treating and aging.
