Carlos Beltran, senior product manager, Hilti, Plano, Texas,
said, while the working principles have not changed, there have
been advances in expanding applications that can be done with
one type of cutting accessory and maximizing battery lifetime
while maintaining productivity and performance. The choice
of the cutting tool depends on the application, and pairing the
tool with the right accessory maximizes the tool’s productivity.
“Multipurpose bits and saw blades are good when the set
of applications/base materials to work with vary from project to project,” Beltran said. “However, contractors with more
specialization in their core tasks will highly benefit from accessories designed for the specific application/base material.
“Metal-cutting applications require more specialization,
based on the type of steel, gauge and desired finish they require.
For instance, stainless steel has a higher toll on generic accessories and will require products that do not contaminate its
antirust properties. That’s why we only recommend stainless
steel rated blades for this application.
“On a different dimension, to achieve better, smoother finishes, the right selection of the blade teeth is critical; thus, the
right selection of the blade for fine finishing versus rough finishing is important on some job sites. Hilti’s focus is to provide
a comprehensive system of tool plus battery plus accessory
that provides the best output in productivity and lifetime of
the whole system,” he said.
Bosch provides a variety of drill bits and saw blades,
including blades for oscillating tools and hole saws.
“Multipurpose bits are preferred for most common
materials,” said Chris Moskaites, product manager,
Bosch. “Specialty bits become required with extreme
materials [e.g., stainless steel, hard concrete, hard tile,
etc.]. Bit life is the consequence for using the wrong
accessory. Users look for more versatility. Multimaterial bits have become very popular because they can be
used in a variety of materials as well as being used with
many tools. Multimaterial drill bits can drill into brick,
block, tile, fiber cement board, wood, plastic and metal.
They can be used with rotary drills, hammer drills and
impact drivers. The newest multipurpose drill bit has
four grinds on the tip. The increased cutting surface
has helped improve the performance of these bits.

“In June, we introduced high-speed auger bits engineered
to work with cordless drills in high-speed mode, and, being
auger bits, they can cut through nails. They have two times the
life of standard auger bits,” he said.
Jared Schmidt, Bosch product manager, discussed the
company’s line of saw blades and hole saws.
“Cutting accessories continue to provide innovation to the
category by providing options for increased lifetime and speed,”
Side-to-side oscillating is very
slight but with an extremely
rapid stroke-per-minute rate.
The most popular oscillating cutting blades have features, such as
curved shape for less vibration and
faster smoother cuts and blades providing longer life.
“Electricians typically use hole saws for cutting holes in electrical boxes and for installing conduit. Popular
diameters are 7/8, 11/8 and 13/8 inches to correspond to common
conduit sizes. Bimetal hole saws are the usual choice, but there
is a variety of specialty products designed for metal that are
increasingly common,” Schmidt said.
