Feature
●Triple edge hexagonal shaft drill bits: The triple blade allows an uniform cut close to a true circle.Compared to conventional dual blades, the load on a single blade is dispersed, giving it excellent durability and cutting performance.It also has excellent stability when rotating, cutting elimination efficiency, and cooling efficiency for long service life
●Stainless steel bit: The groove shape is ideal for stainless steel and allows for a smooth hole with minimal welding.Material for machining: stainless steel, hard work material, general steel, light metal (iron, aluminum, copper), wood, resin, etc.An indispensable tool for household DIY, drilling pilot holes, etc
●Cobalt high speed steel drill bits: HSS-Co M35 steel drill has been treated with an AlTiN titanium nitride aluminum coating on the surface and has a hardness of HRC89.The strong screw shape is lightweight, the special ultra-multi-layer coating allows for quick drilling, and it has excellent heat resistance and reduced heat produced during use.Improved high temperature and grinding resistance of the bits, ideal for high-speed drilling
●Scope of application: This is an excellent drill set with newly designed blade tips, short-sized to reduce drilling deviations, and can be used to make precise round holes in material.The shape of the shank is hexagonal, so it is compatible with rechargeable drivers, rechargeable drills, screwdrivers, and impact drivers
●Product Specifications: Set of 8 frequently used drill bits.Set includes: 3.0, 3.2, 4.2, 4.5, 5.0, 6.0, 6.5 mm, storage case.Material: HSS-Co M35 Steel.Surface treatment: AlTiN titanium nitride aluminum coating.Shaft Diameter: 1/4-inch (6.35 mm) hexagonal shank
Description
[Note]
Because it is sharp, please use it vertically.
Regular ironwork drills temporarily heat resistant with titanium coating, but the blade will not wear out and cut before the blade is hot and the result is a higher coefficient of wear and burn.Stainless steel is harder and more sticky than ordinary iron, so when used for work, we recommend Cobalt Hiss (HSS-CO) that is harder and more resistant to wear and tear.
Product Name : Hexagonal Shaft Short Drill Blade Edge: Tri-Blade Material: Cobalt High Speed Steel (HSS-Co/M35) Surface Treatment: TiAlN Titanium Coating Hardness: HRC89 Size: 3.0, 3.2, 4.0, 4.2, 4.5, 5.0, 6.0, 6.5 mm Set Includes: 8 pcsShank diameter: 1/4 inch hex shank (0.25 inch (6.35 mm)); Storage: Blister 1 Uses: For drilling holes in stainless steel, iron, copper, aluminum, wood, resin, etc.
Spiral Drill Features
Material: Cobalt High Speed Steel HSS-CO (TiAIN Titanium Nitride Aluminum Coating)
Titanium Nitride Aluminum Coating: Outstanding abrasion resistance and heat resistance, no coolant water needed.We recommend using cutting oil to reduce friction heat and use cutting oil for a long time.
Three Blade Drill:
The specially formulated blade edge greatly improves the drilling ruler and greatly improves the cutting performance.By shortening the overall length, the drill blade is less shaking when using electric tools, and precise drilling.The special blade edge construction reduces cutting resistance and reduces battery wear on the charging tools.There is less burrs after drilling and it allows for clean holes.

The special blade edge is sharper than conventional products, improving stability and cutting efficiency for smooth drilling work.Cobalt High Speed Steel for long lifeThe thinning of the blade and the ideal screw angle make it sharp, so it will stick to the material well and does not slip. |
Material: Stainless steel, iron, aluminum, copper, wood.The hexagonal shank allows you to attach it to an electric drill with one touch.Ideal for drilling holes (under drilling) iron, aluminum, stainless steel, copper, wood, resin, etc.Ironworking drill and step drill are included in the set. |
The short size makes it hard to shake and allows for precise and clean holes. Titanium coating for better heat resistance and long lasting sharpness. If the blade edge is damaged, The drill edge has a special shape, so it cannot be re-sharpened with the same shape.When polishing a damaged edge, the blade angle can be 118° or 135° depending on the type of grinder. |
