DAYDOOR 1-1/2"Diamond Hole Saw Bit with Pilot Drill Bit(3/8"Triangle Shank)

• 2-Piece Diamond Hole Saw Bits: This set includes 2pc 38mm (1-1/2") Diamond Hole Saw Bit and 1pc Hex Wrench, offering flexibility for various drilling needs, such as kitchen renovation, bathroom decoration, house construction, commercial building decoration, automobile repair and modification, equipment manufacturing and maintenance, outdoor furniture installation, and fence installation and so on
• Precise Positioning: The Diamond Hole Saw Bits includes a detachable centering pilot drill, which locks accurately onto marked positions to ensure a precise start on glass and smooth surfaces. The detachable pilot drill can prevent the main drill bit from wandering or slipping, making the Hole Saw Bit reliable for consistently creating precise holes in ceramic tiles
• Durable and Robust: Crafted from high-carbon steel using an advanced vacuum brazing process, these diamond core drill bits feature high-quality diamond grit firmly bonded to the surface. This ensures high hardness, excellent wear resistance, rust resistance, and a long service life
• Enhanced Performance Design: The hollow body with U-shaped grooves facilitates fast debris removal and heat dissipation, preventing ceramic drill bit burnout. The 3-flat 3/8" shank provides a secure grip and reduces slippage for safer operation. A thickened diamond coating creates a sharper edge, enabling precise, chip-free cutting. Special high-temperature treatment allows optimization for both dry and wet drilling: dry drilling enables fast cutting, while wet drilling helps extend the drill bit's lifespan
• Versatile Use: This Diamond Hole Saw Bits set is ideal for ceramic tiles, ceramic floors, rock, porcelain, glass, marble, granite, stone, and jade. Designed to create clean, precise holes in hard materials, it comes packaged in a box for easy retrieval and safe storage
