Two-speed magnetic drill
offers 6-in. depth of cut
Hougen Mfg. Inc. has released a new portable magnetic
drill, the HMD918. It features a high-torque motor and extended 6-in. drilling depth to give metal fabricators more
options to drill deep holes in steel, whether a solid piece
of material or multiple stacked plates.
A 2-gal. pressurized coolant bottle attaches to the drill
arbor, providing pressurized coolant to the cutter no matter the position of the drill. The mag drill pilot light allows
the operator to line up the hole in all lighting levels. The
two-speed motor helps increase torque when using large-diameter cutters or drilling deep holes.

Nozzles for 2-D laser cutting machines
reduce cutting gas usage 70 percent
TRUMPF has introduced the Highspeed and Highspeed Eco nozzles, which
the company says boost the feed rate by up to 100 percent for solid-state laser machines that employ fusion cutting with nitrogen. With this technology,
the piercing process is faster, and laser power does not need to be increased.
These new cutting processes allow for a nearly twofold increase in sheet
throughput compared to standard cutting, according to the company.
The nozzles’ design uses less cutting gas: 40 percent less nitrogen on average with the Highspeed, and 70 percent less with the Highspeed Eco.
The scope of applications is now broader for 8-k W lasers used in fusion cutting. The laser now can fusion-cut sheets as thick as 0.5 in. instead of 0.4 in. as
in the past.
The Highspeed process makes use of a biflow nozzle. The laser beam and
some of the cutting gas pass through the center of this nozzle. The rest forms
a secondary flow around the principal flow to concentrate it onto the kerf, expelling molten material more efficiently.
The Highspeed Eco is fitted with a sleeve that forces the gas directly into
the kerf, ensuring that little or no gas flows off to the side. While this moving sleeve glides across the material during fusion cutting, the nozzle remains
0.06 in. from the sheet surface. This helps to ensure the nozzle can withstand
any spatter generated during piercing.

Combination torch features new cutting
Victor®, an ESAB
brand, has introduced
the Victor Plus Torch,
a heavy-duty, high-capacity combination
torch that features
the new CA 2460+ cutting attachment and
WH 315FC+ handle.
The handle incorporates built-in flashback arresters and reverse-flow check valves, but its design enables high gas flow capacity. It can run up to a #15 MFA heating nozzle,
whereas the standard 315 handle could run up to a size #8.
The CA 2460+ cutting attachment features a contoured cutting oxygen lever,
and the torch head uses thick brass to improve abrasion resistance.
