Set of 5 Step Drill Bits, Step Milling Cutters with Titanium Coating for Steel, Wood, Plastic, Brass, Aluminum, PVC, Double-Slotted Conical Cutting Drill Bits

【High-Quality Materials】Classic high-speed steel, titanium coating on the surface, proven performance and durability in drilling holes in plastics, wood, aluminum, copper, stainless steel, and many other types of sheet metal. Titanium alloy drill bits are particularly suitable for processing copper and aluminum parts/die steel/spring steel/cast iron parts/iron and other metal materials.

【Easy to Drill】The double-slotted spiral groove design prevents slippage, quickly removes chips and deburrs the hole, the pressure is low, drilling and cutting are faster and smoother; it can achieve a faster, more stable, and smoother cut. The hole can be automatically chamfered to clean the drill bit.

【Double Cutting Blade & Three Rods】The double cutting blades and X-type opening design ensure faster and smoother cutting; the 3-sided rod design prevents the drill bit from slipping; with minimal pressure, the set can cut through wood, sheet metal, steel, and other surfaces.

【Uses】Suitable for home DIY projects and general building supervision. Widely used for cutting various materials such as wood, plastic, thin metal sheets, thin aluminum sheets, and tin side panels. It is suitable for parts with a hardness of less than 25°, such as carbon steel, with a plate thickness of less than 5mm

【Save Time】A range of assorted pitch sizes allows you to drill or enlarge different holes in one drill bit without constantly changing bits. The pitch is laser-engraved into the metal, so it can be drilled precisely and won't wear down even with extended use.

Product Description

Features:

Superior Quality.

This Step Drill Bit replaces 50 individual drill bits. The two-flute design allows for faster and more even cutting. The triangular shank (TRI-FLAT) prevents slipping in the chuck. Cobalt coating for a more even and cooler cut, titanium coating to reduce friction and run cooler. The large drill bit has a 3-sided shank, and the smaller drill bits have a hexagonal shank to prevent the chuck from slipping.

Automatic deburring of holes during drilling.

Fast and durable work steel.

Padded aluminum protective case included.
