Hole Saw

Hole Saws for Drilling Large Round Holes in Wood, Metal, and Construction Materials

Hole saws are cylindrical cutting tools designed to drill clean, large-diameter round holes in wood, metal, plastic, drywall, fiberglass, and tile — sizes that exceed the practical range of standard twist drill bits. Hole saws in the Philippines are essential equipment for electricians cutting outlet and conduit boxes, plumbers installing pipe penetrations, HVAC technicians cutting duct openings, fabricators producing circular cutouts in sheet metal, carpenters fitting door hardware, and maintenance teams handling renovation and installation work. Compatible with standard 220V drills and 18V/20V cordless drivers used across Philippine job sites and workshops, hole saws deliver the precise, repeatable circular cuts that handheld jigsaw or rotary tool methods cannot match.

This collection covers the full hole saw range — bi-metal hole saws for general-purpose drilling, carbide-tipped (TCT) hole saws for stainless steel and hard materials, diamond hole saws for tile and ceramic, wood hole saws for carpentry, multi-size hole saw sets for kit-building, and the matching arbors, mandrels, and pilot drill bits required to mount and center every cut. Whether you wire residential units in Quezon City, install plumbing in a Makati high-rise, fabricate steel panels in Cebu, or run general contracting in Davao, KHM Megatools carries professional-grade hole saws sized from small electrical knockouts to large 6"+ diameter installation cuts.

Hole Saw Price Range in the Philippines

Hole saws span a wide price range based on construction (bi-metal, carbide, diamond), diameter, and brand. Bulk and contractor pricing is available for electrical contractors, plumbing crews, fabrication shops, and installation teams who consume hole saws in volume.

• Entry-level / DIY grade: Small bi-metal hole saws (15mm–25mm), basic wood hole saws, and pilot drill bits ranging from ₱150 to ₱700 — practical for occasional installation work
• Mid-range / professional installer grade: Standard bi-metal hole saws (25mm–65mm), TCT hole saws (16mm–30mm), arbors, and small multi-piece kits ranging from ₱700 to ₱2,500 for daily trade use
• Professional / industrial grade: Large-diameter bi-metal hole saws (75mm–150mm+), TCT hole saws for stainless steel, diamond hole saws, and complete installer hole saw sets ranging from ₱2,500 to ₱15,000+

Choosing the Right Hole Saw

Why Professionals Use Hole Saws

• Produce clean, accurate circular holes that twist drills, jigsaws, and rotary tools cannot match in larger diameters
• Faster than step bits or jigsaws for repeated installation cutouts in electrical, plumbing, and HVAC work
• Wide diameter range — from small electrical box knockouts to 150mm+ duct and pipe penetrations
• Material-specific options (bi-metal, TCT, diamond) let installers match the saw to the substrate
• Compatible with standard 220V corded drills and 18V/20V cordless platforms used on Philippine job sites
• Reusable and resharpenable for production use, lowering tool cost per hole over project lifetime

Expert Tips for Using Hole Saws

• Use cutting fluid or coolant when drilling stainless steel and thicker mild steel — this extends tooth life dramatically and prevents work hardening that destroys hole saws prematurely
• Run hole saws at slower RPMs than twist drills — large diameters need lower speeds (often 200–500 RPM for metal, 800–1,500 RPM for wood) to avoid burning teeth and overheating
• Clear chips frequently — pull the saw out of the cut every few seconds to eject swarf; clogged hole saws stall the drill, burn the cut, and shorten saw life
• Always use the matching pilot drill bit and arbor — the pilot centers the cut and prevents the saw from walking; replace bent or dull pilot bits before they damage the workpiece

Frequently Asked Questions

What is a hole saw and what is it used for?

A hole saw is a cylindrical cutting tool that drills large round holes in wood, metal, plastic, drywall, and tile. It cuts only the perimeter of the hole rather than the full diameter, leaving a removable slug — making it faster and more efficient than twist drills for hole sizes typically above 15mm. Common uses include electrical box and conduit cutouts, plumbing pipe penetrations, HVAC duct openings, door hardware installation, and fabrication cutouts.

Can a hole saw cut through stainless steel?

Yes, but only with the right type. Bi-metal hole saws can cut thin stainless steel slowly with cutting fluid, while TCT (carbide-tipped) hole saws are specifically designed for stainless steel, cast iron, and hardened metals — they cut faster and last longer in tough materials. Always use cutting fluid, low RPM, and steady feed pressure when drilling stainless to prevent work hardening.

Do hole saws work with cordless drills?

Yes. Most bi-metal and wood hole saws up to about 65mm diameter work well with 18V or 20V cordless drills. For larger diameters (75mm and up) or when cutting metal, a corded drill or magnetic drill machine delivers more torque and continuous power. Always use a drill with adjustable speed and slow the RPM down for metal cutting.

What's the difference between a hole saw and a step drill bit?

A hole saw cuts a single large diameter and works on thick materials including wood, masonry, and metal up to its cup depth. A step drill bit (or unibit) cuts multiple progressive diameters in one bit, but only works on thin sheet material — typically up to 4–6mm. Use hole saws for thick stock, large diameters, and dedicated sizes; use step bits for thin sheet metal and electrical panels where you need quick adjustable sizing.

Do hole saw bits come with a warranty?

Warranty varies by product. Hole saws are generally considered consumable cutting tools and may not include warranty coverage. Please check the individual product page first. If warranty information is not stated, refer to our warranty policy for guidance. Learn more about Warranty Policy »
