Drill and Burr Series Offers Various Geometries for MRO

The Precision Twist drill brand of cutting tools by Dormer Pramet has released a selection of affordable HSS drills and carbide rotary burrs under the name PrecisionLight, designed to meet the needs of the maintenance and repair professional. 

The HSS drill family includes lengths categorized as “screw machine,” “jobber” and “mechanics” as well as reduced-shank versions. Said to provide both versatility and performance in a variety of materials, the range contains conventional 118-degree point geometries as well as 135-degree self-centering split points for more challenging applications. The range covers most ferrous applications suitable for use in portable drilling, drill presses and other operations, the company says.

The carbide rotary burr range consists of two new material-specific geometries. The double cut (DC) geometry is suitable for machining steels, while the aluminum cut (FM) is for machining aluminum and other nonferrous materials. Available in a variety of shapes, both geometries are said to offer improved operator control and generate less heat, which contribute to tool life and productivity. The company says the designs offer improved performance and up to 50 percent higher metal removal rates, compared to standard carbide burrs.
