High-Quality Construction: These drill bits are fashioned from robust HSS steel ensuring durability and longevity. Perfect for drilling holes in a myriad of materials such as steel, brass, wood, and plastic.
Advanced Craftsmanship: Our titanium-coated drill bits are designed to reduce heat and friction. We’ve heat-treated our products for enhanced durability and polished them to guarantee perfectly round holes time after time.
Efficient Design: Boasting a three-sided shank that prevents slipping during use, each bit is precisely marked with the depth diameter on each step. The two-flute design allows cleaner cuts as well as speedy and efficient operation.
Versatile Functionality: This set contains three common sizes of drill bits suitable for deburring, chamfering, cutting or expanding holes. Compatible with various tools such as pistol drills, hand drills charging drills, or bench drills.
Balancing Speed & Safety: To optimize drilling efficiency while maintaining safety standards; the user should apply downward force when using different rotating speeds. However excessive force can cause premature wear to the edges.
