OSUKA Concrete Hole Saw 2.5" (63 mm) Model OSHS4022

The OSUKA OSHS4022 Concrete Hole Saw is a diamond-tipped core bit designed for fast and efficient drilling through masonry materials. With a 2.5-inch (63 mm) diameter, one of the most commonly used sizes among air-conditioning and electrical technicians, it creates clean openings that are ideal for routing refrigerant pipes, electrical conduits, water pipes, and other installation systems. Built for durability and heavy-duty applications, the OSHS4022 features a seamless steel body, large debris-removal slots, and laser-welded diamond cutting segments for superior strength, cutting speed, and long service life.

Key Features

• Seamless Steel Construction : Manufactured from a high-strength seamless steel tube, providing excellent durability and resistance to bending or deformation during demanding drilling applications.
  
• Large Debris Removal Slots : Designed with oversized extraction slots to efficiently remove dust and debris, helping prevent clogging, reduce heat buildup, and improve drilling speed.
  
• Laser-Welded Diamond Segments : The diamond cutting teeth are laser-welded to the barrel, creating an exceptionally strong bond that withstands heavy-duty use and extends tool life.
  
• Diamond-Tipped Cutting Teeth : High-quality diamond segments deliver fast drilling performance, clean hole finishes, and outstanding wear resistance for long-lasting cutting efficiency.
