P.I.T. 3-in-1 4.5 in Cut Off Wheel Set - Multi-Material Cutting Pack

Our review of the P.I.T. 3-in-1 Set finds it best suited for DIYers, renovators and tradespeople who need a small, versatile pack of cut-off wheels for an angle grinder. The set delivers on versatility and value: three 115 mm (4.5 in) discs with a 7/8 in (22.2 mm) arbor fit standard grinders and cover metal, masonry and wood tasks. The single biggest reason to buy is the combination of a diamond vacuum-brazed metal blade and a tungsten carbide multi wheel that handle a wide range of materials with fewer blade changes.

Key Features

• Three-pack convenience: Includes three 115 mm discs so the user has replacements or different blade types on hand for multi-step jobs.
• Arbor compatibility: The 7/8 in (22.2 mm) arbor fits common angle grinders so installation is straightforward on most tools.
• Diamond vacuum-brazed metal blade: The industrial diamond grains are permanently brazed to the steel core for heat resistance and long life when cutting hard materials like marble and granite.
• Tungsten carbide multi wheel: Carbide grit protrudes beyond the wheel face to cut through wood with nails, plastic and laminate with reduced clogging and better chip removal.
• Ultra-thin steel body and round-hole design: Thin profile and cooling holes reduce heat buildup, improve dust removal and help maintain blade shape for cleaner cuts.
• Broad material list: Designed to tackle metal, stainless, aluminum, PVC, ceramic, wood, plasterboard and more, reducing the need to buy separate specialty blades.

Who It's For

The set is aimed at homeowners, hobbyists and light-professional users who value a multi-purpose kit that covers most cutting needs without carrying a full inventory of specialized discs. It is particularly useful for renovation tasks where one might encounter tile, plaster, plastic and occasional metal or masonry.

Those who should look elsewhere include heavy industrial users or contractors who need high-volume, purpose-specific production blades for continuous cutting of reinforced concrete or large quantities of metal; a dedicated professional would likely prefer full-size industrial blades rated for extended continuous use.

Pros & Cons

Pros

• Good value three-pack that reduces downtime and trip frequency to buy replacement discs.
• Vacuum-brazed diamond blade and carbide multi wheel both provide noticeably long life on abrasive materials.
• Thin steel body and cooling holes improve cut quality and reduce heat-related deformation.

Cons

• Not a substitute for full-size industrial specialty blades in continuous professional production environments.

Our Verdict

The P.I.T. 3-in-1 4.5 in cut-off wheel set is a practical, cost-effective choice for DIY enthusiasts and light trades work because it combines diamond and carbide technology in a single small pack. It delivers versatile cutting performance across a wide range of materials and is good value for anyone who needs reliable, general-purpose discs rather than dedicated high-volume production blades.

Frequently Asked Questions

Will these discs fit my angle grinder?
Yes, they use a 7/8 in (22.2 mm) arbor which suits most common 4.5 in angle grinders.

Can I cut steel and masonry with the same disc?
The set includes separate blade types; the diamond metal blade and carbide multi wheel cover masonry and metal respectively, so use the correct disc for each material.

Are these safe for occasional professional use?
They are suitable for light professional tasks and renovation work but heavy continuous industrial cutting is better served by dedicated production blades.
