July 20, 2020 - Kennametal, Pittsburgh, has introduced an expansion its solid carbide drilling portfolio, the HPX drill for high performance, large volume drilling in steel. Designed to quickly and efficiently punch holes up to 8 x D in any ISO-P steel material, the HPX drill provides up to twice the tool life and three times the productivity compared to competing products, even in dry or minimum quantity lubrication (MQL) applications.

Key differentiators

What makes the HPX drill the superior choice for Steel applications? The difference is in the design. Steels are used for a wide variety of automotive, commercial, and industrial applications, often in production volumes where maximum tool life and throughput is critical. Yet steel creates a high degree of mechanical loading during drilling operations resulting in forces that lead to rapid tool wear and chipping of the tool's more vulnerable corners. Kennametal has eliminated this failure point by applying a small corner chamfer and straightening the HPX drill's cutting edges. Together with the rounded margin lands running down the length of the flutes, this serves to stabilize the drill while reducing friction.

Built-up edge is another common problem when drilling alloy steels. The HPX drill's straight cutting edge helps eliminate some of this, but the real clincher is the drill's optimized edge preparation. This gentle hone further reduces the friction that leads to built-up edge, as do the tool's highly polished flutes. Couple that with a carbide grade designed specifically for steel—KCP15B—and a proprietary multilayer AlTiN coating, and the HPX drill sets a new standard for tool life in high-volume ISO-P drilling.

Lower forces, even better reliability

Special gashing on the HPX drill improves the chip formation and curls a smaller chip. The material specific HPX point geometry creates significantly lower cutting forces, which works great for machines with lower spindle capabilities, unstable cutting conditions, or unstable workpiece clamping. A continuous cross section makes the HPX drill more resistant against tool breakage, and the ultrahigh polished chip flutes ensure superior chip evacuation.

Manufacturers wishing to turn off their high-pressure coolant pumps in favor of dry cutting or MQL systems, efficient chip evacuation along with low-friction cutting is a must, and the HPX drill delivers on both counts. In fact, the drill comes equipped with a leakproof MQL interface that meets DIN 6535 and 69090-03 standards—no more special orders or in-house modifications.

July 10, 2018 -  Walter Surface Technologies, Windsor, Connecticut, has fully redesigned its ICECUT™ line of powerful magnetic drilling units and annular cutters.

Think ICECUT™ and think power, versatility and mobility. At 22 lbs. and 27 lbs. respectively, the ICECUT™ 100 and ICECUT™ 200 mag drills are lightweight champs that punch above their weight.

Looking for powerful, efficient drilling made safe and easy? ICECUT’s ACCUDRILL™ technology protects against overload, overheating and reduces cutter breakage risk.

ICECUT’s ergonomic control panel eases operations with centralized controls that enable efficient drilling on either side of the unit.

ICECUT’s mandrel support absorbs vibrations for stability and perfect centering, ensuring the motor and chuck are perfectly aligned. Operators get precise cutting with little chance of cutter damage.

ICECUT’s lightweight, ergonomic and smooth-grip handle makes unit positioning and drilling operations easy. The unit also features a separate, quick-release and reversible handle for easy positioning in confined spaces.

“Walter’s newly redesigned ICECUT™ units are mobile, lightweight and powerful enough for any job site,” explains Ryan Boyd, Product Manager, Tooling and Power Tools. “There’s a tremendous range of features that guarantee the most productive drilling system, and with our ACCUDRILL™ pressure guide, there is almost no risk of motor overloading, overheating, or premature cutter breakage.”

ICECUT’s integrated wiring eliminates obstructions when drilling or repositioning the unit. No wires mean no mishandling failures. “That’s convenience,” says Boyd.

The drilling unit’s steel sliding guard keeps operators safe, too. Engage this safety feature for worry-free drilling, free of errant chips and lubricant splash.

Operators will also appreciate ICECUT’s easy maintenance. Direct access to the unit’s carbon brushes make tune-ups simple and keep ICECUT’s powerful motor operating at maximum power.

When mobility is key, check out the ICECUT™ 100. Its one-speed, 850-watt motor delivers 600 RPMs at 8.5 amps.

When versatility and power is a must, look to the ICECUT™ 200. Its two-speed 1200-watt motor delivers 300-600 RPMs at 12 amps and is ideal for a wide range of job site operations.

What’s power without drilling speed? Walter’s latest core cutters are guaranteed to drill more holes faster. The company’s redesigned annular cutters are toughened with a sophisticated mixture of high-speed steel and aluminum for longer life.

More resistant to instant impact and stress when drilling under load, these annular cutters are less brittle and impervious to deformation.

“ICECUT is a simply a versatile, powerful and safe line of magnetic drilling units and annular cutters,” says Boyd. “It’s the ultimate core cutting system that helps our customers work better.”
