PMT CORE BIT 22MM

The PMT Core Bit 22mm (also referred to as the PMT 22mm Diamond Core Drill) is a specialized diamond-tipped core drill bit from PMT PM Tools & Abrasives, an Indian brand known for affordable, durable power tool accessories. Designed primarily for creating precise 22mm diameter holes in hard materials like granite, marble, concrete, stone, and masonry, it's a popular choice for plumbers, electricians, fabricators, and DIY enthusiasts working on installations such as pipe fittings, railings, or tile work. The bit features a segmented diamond edge for efficient cutting and reduced heat buildup, making it suitable for wet or dry drilling (wet recommended for longer life). It's compatible with standard angle grinders, core drills, or rotary hammers with a matching arbor/shank (typically 10mm hex or M14 thread).

Key Features

• Material and Design: High-quality diamond-impregnated segments for aggressive cutting; chrome-plated body for corrosion resistance and easy cleaning.
• Hole Diameter: 22mm (precise for applications like 3/4" pipe installations or stainless steel railing supports).
• Drilling Depth: Up to 100-150mm (depending on model variant; extensions available).
• Shank/Arbor: 10mm hex shank for quick changes; fits most 100-125mm angle grinders.
• Applications: Ideal for drilling through reinforced concrete, brick walls, granite countertops, or marble slabs; great for plumbing, HVAC, and fabrication jobs.
• Durability: Laser-welded segments ensure longevity (up to 50-100 holes in concrete, based on user tests); works with water cooling for dust-free operation.
• Safety: Low vibration and no-slip grip; always use PPE and secure the workpiece.
