GRAPHITE Carbide-Tipped Hole Saw Set, 6 Pieces (19–64 mm) with 2 Arbors and 2 Pilot Drills, 10-Piece Kit

Drilling clean, precise holes in wood, plasterboard, plastics, and light building materials often becomes a struggle with standard bits that dull quickly or wander off-center. This GRAPHITE hole saw set solves that problem by pairing high-carbon steel bodies with tungsten carbide teeth, so you can cut through abrasive materials without burning through bits. The kit includes six hole saws (19, 25, 32, 38, 51, and 64 mm), two arbors with hexagonal shanks, and two HSS pilot drills, all packed in a durable plastic case for easy transport and organization.

Who is it for

This set is built for electricians, plumbers, carpenters, and serious DIYers who need reliable, repeatable holes in softer construction materials. If you regularly install downlights, run cables through studs, or cut openings for pipes and vents, the carbide-tipped teeth stay sharp longer than standard bi-metal saws, saving time and money on replacements.

Main features

• Six carbide-tipped hole saws: 19, 25, 32, 38, 51, and 64 mm diameters cover the most common installation sizes.
• Tungsten carbide cutting edges on high-carbon steel bodies deliver fast, clean cuts in wood, plasterboard, plastics, brick, aerated concrete, and similar light building materials.
• Two arbors with hexagonal shanks fit standard electric and cordless drills, preventing slippage under load.
• Two HSS pilot drills center each hole saw for accurate starts and reduced wandering.
• Maximum drilling depth of 25 mm handles most sheet materials and thin walls.
• Durable plastic case keeps all 10 components organized and protected between jobs.

Tips

For best results, start the hole saw at a slight angle to create a guide groove, then straighten the drill as you apply steady pressure. Clear chips frequently to prevent overheating, especially in plastics and plasterboard. Use a slow speed for larger diameters (51 mm and above) to maintain control and extend blade life.
