Drilling & Boring

Sandvik Coromant offers a deep hole drilling strategy using its CoroDrill 861-GP and 861-GM drills in this brief video supplement to "A Happy Medium," a feature article in the October 2021 issue of Cutting Tool Engineering that delves into effectively drilling austempered ductile iron.

A little knowledge about key subjects goes a long way when shopping for a reaming tool.n

The UNE series of gundrilling machines are a good fit for high-volume/low-mix or low-volume/high-mix manufacturing environments.

Branding for Gorilla Mill, a manufacturer of carbide drills, endmills and cutting tools, is simian-themed, aggressive and fun, and it comes with the tagline "Weapons of Mass Production." The company has grown in employees, distributors and a diverse spread of customers.

AH9130 is Tungaloy's latest PVD technology specifically designed for high-performance drilling applications. With better wear resistance compared with existing first-choice grade AH725, the grade delivers extremely long tool life in drilling applications, particularly of carbon steel and alloy steel.

The 18-Inch Gear Head Bench Drill Press all-gear head driven transmission delivers full power at any speed, driving the cutting tools at nearly 100% of the available horsepower. To ensure positive, quiet operation, the bench drill uses combined steel and reinforced fibers. The ground steel clutches enhance its performance and strength.

Designed for extreme drilling in steels, Guhring's RT100 XF drill family delivers. The carbide grade developed for the RT100 XF balances hardness and toughness.

Finishing boring processes with the right tools boosts accuracy and surface quality.

Made of hardened steel, it is extremely robust and resistant to all external mechanical influences. It can be used on serrated tool bodies and Alu-Line slide tools in the diameter range from 3.937" – 128.15" (100 mm – 3255 mm). Additionally, this precision boring tool can be adjusted without the aid of the readout.

The new DB133 drills, with their 140° point geometry, are available in diameter range from 1/32-5/64 in. and 0.5 to 2.95 mm. Length to diameter ratios (L/D) of 5, 8 and 12 x Dc are standard.

The Flex drills are available in steps of one hundredth millimeter for drilling depths of 50 x D, as well as the "shorter" lengths of 20 x D and 30 x D.

Modern moldmaking must be efficient.
