WHAT ARE THE DIFFERENT TYPES OF HOLE SAWS?
2
A hole saw or hole cutter is a specialist drill
bit type designed to allow the user to bore out a
circular hole with a wider diameter than would
normally be produced by most standard bits.

TYPES OF HOLE SAWS
1. CARBON STEEL
A DIY specialist or enterprising home improver, a
simple general-purpose carbon steel Hole saw that
performs effectively. While not the most durable,
for use with softer materials, including wood,
non-laminated plastic, and plasterboard, carbon
steel hole saws are suitable.
2. VARIABLE PITCH BI-METALLIC
Bi-metal construction increases protection by
eliminating the risk of breaking, so consider
them to be a decent step-up to deal with or
operate over longer periods with slightly harder
materials. Many boast high-speed steel-reinforced
teeth for quicker cutting, and variability allows
you to cut according to your chosen material at
different speeds.

3. DEEP CUT VARIABLE PITCH BI-METALLIC
The deep cut variable pitch bi-metallic hole saw
drill is not coincidentally called and will have
a cut depth of up to 42.5 mm. Otherwise, the
properties and advantages of the regular
bi-metallic are preserved.
4. CONSTANT PITCH SMOOTH CUT
The smooth cut hole saw of constant pitch uses
high-speed steel with a rugged alloy body.
Hardened, abrasion-resistant, and heat-resistant,
they are made of stainless steel, tools, and mild
steel for cutting. Also working well are
plasterboard, wood, and thin plastics.

5. TUNGSTEN CARBIDE TIPPED (TCT)
Tungsten carbide tipped teeth are suitable for
those who expect to use their hole saw regularly
and for extended periods, offering fast cutting
action and excellent durability.
6. WELDED SHANK SOFFIT CUTTER
The base plate is welded to a non-detachable
arbor, and the saw is made of high-speed steel
with a variable tooth pitch. The large diameter
makes them appear tailor-made in soffit boards
for cutting vent holes, and they work well with
plywood, metal, and PVC.

7. DIAMOND-EDGED HOLE SAW
These hole saws are either polished or infused
with diamonds to display a conspicuous absence of
teeth. The hardness and durability are excellent,
so no barrier is high heat and persistent
resistance. Generally speaking, you can use them
to drill into ceramic tiles.
8. MULTI-HOLE SAW
Built to be used for cutting a number of
different diameter holes, when it comes to
material, the multi-hole is notoriously
undiscerning. They can all be sliced into the
wood, non-laminated plastics, plasterboard,
chipboard, plywood, and non-ferrous metal (except
stainless steel).

APPLICATIONS OF HOLE SAWS
There are several different types of Hole saws
and accessories available for different kinds of
applications and working surfaces.

• Drilling holes for wiring and cable routing runs.
• Make cutouts for downlights, fittings, or light
  fixtures in ceilings for placement.
• Fitting sinks, baths, and worktops with taps and
  other hardware.
• Projects for general joinery, woodwork, and DIY
  projects.
• Installation of duct runs or drainage pipes
  through kitchen units and walls.
• Boring into masonry for better ventilation or
  waste removal purposes.
• Installing door and cabinet hardware, including
  handles, locks, and rails.
