<p>High-quality material structure: Hole saw made of HSS and superior bimetal for higher load capacity; Ultra-high toughness, high cost performance, solid performance and quality assurance, not easy to break, hardened grooves, long wear resistance and long service life.</p> <p>Sharp tooth: The hole drill bit set offers impact-resistant and abrasion-resistant teeth. The tooth shape is neat, the vibration is small, and it can be quickly compensated when the hole is opened, making the operation more stable.</p> <p>Cutting design: The wood drill with the non-binding design with neat edges cuts smoothly and easily. And the drill spring automatically pushes the disc out of the saw immediately after drilling the hole.</p> <p>Easy Chip Removal: The chip removal groove attached to the side of the hole saw, the metal drill bit set can quickly discharge chips, improve the removal speed of cylindrical iron filings in the hole, and do not cause cracking and blocking phenomena.</p> <p>Widely Used: The bimetal wood drill bit set is widely used in gypsum board, steel, aluminum, non-ferrous metals, copper, brass, wood, plastic, PVC and other materials. It is very suitable for drilling holes in desks, doors, furniture and cabinets. Suitable for bench drill, electromagnetic drill, gun drill, impact drill, etc.</p> <p>Feature:</p> <p></p> <p>1. Unique Design: Bimetal hole saw with forward and backward inclined tooth shape, fast cutting speed compared to ordinary drill saw with identical teeth, not easy to jam or pull teeth.</p> <p></p> <p>2. Wear-resistant without shaking: High-speed steel hole saw, sharp cutting edge, high hardness, wear during operation, chips, reliable. Hole saws cut precisely without wobbling.</p> <p></p> <p>3. Complete Set Size: The bimetal wood drill set contains the 9 most common saw blade sizes: 0.63" (16mm), 0.7" (18mm), 0.78" (20mm), 0.86" (22mm), 0.96" (25mm), 1.17" (30mm), 1.26" (32mm), 1.38" (35mm), 1.49" (38mm)</p> <p></p> <p>&nbsp;</p> <p></p> <p>Specification:</p> <p></p> <p>Material: M42 bimetal</p> <p></p> <p>Quantity: 9pcs</p> <p></p> <p>Size: 0.63" (16mm), 0.7" (18mm), 0.78" (20 mm), 0.86" (22 mm), 0.96" (25 mm), 1.17" (30 mm), 1.26" (32 mm), 1.38" (35 mm), 1.49" (38 mm)</p> <p></p> <p>Color: Red</p> <p></p> <p>Cutting Depth: 20 mm.</p> <p></p> <p>Item Weight: Approx. 760 g</p> <p></p> <p>&nbsp;</p> <p></p> <p>Package Contents:</p> <p></p> <p>9 * Bi-Metal Hole Saws</p> <p></p> <p>&nbsp;</p> <p></p> <p>Warm Tips:</p> <p></p> <p>1. Use a hole saw wood set. Don't forget to install a mounting plate. This is important. Placing the mounting plate between the blade and the nut prevents damage to the blade.</p> <p></p> <p>2. It is recommended to use a machine with a drilling speed of 1000 rpm or less as it can extend the life of the hole saw.</p> <p></p> <p>3. Wear safety glasses and gloves when cutting, as it is safe to do so.</p> <p></p> <p>4. After circular cutting metal, apply a small amount of antioxidant oil to the surface of the filter to prevent natural oxidation and increase the service life.</p> <p></p> <p>5. Wood circular saw set, which is not suitable for thick metal, becomes very rich.</p>
