Product Features：
FOCMKEAS Heavy Duty TCT Hole Saw is a professional tool for thick metal drilling.
With core advantages from high-quality materials and precision design:
☆TCT tungsten carbide tip offers superior hardness, paired with a titanium-plated HSS pilot drill for rust resistance and long service life;
☆Three-blade layered cutting structure reduces resistance while enabling high-speed drilling, creating smooth, burr-free surfaces;
☆Triangular shank fits various drills (rechargeable drill, handheld drill, bench drill，etc.) for stable clamping without slipping, suitable for professionals and DIYers.
Usage Instructions：
☆Installation: Secure the pilot drill in the hole saw center with the L-shaped hex key to ensure firmness;
☆Positioning: Pre-drill a shallow pit (about 1-2mm deep) on the surface with the pilot drill to avoid deviation;
☆Drilling: Start the drill, maintain low-speed steady feed (500-800RPM recommended for hard metals), and add coolant in time during continuous drilling to cool down;
☆Safety: Wear safety goggles and gloves throughout, avoiding direct contact with high-temperature tips.
Scope of Application：
