Feature
●Hex shank: 4-piece spiral groove step drill set made of HSS stainless steel bit holder peeling drill cone drill cone drill metal drill bit set 4-32 mm, 4-20 mm, 4-12 mm, 5-35 mm). HSS step drill hex shank is suitable for most drills or drills with 1/4 inch chuck, can be firmly installed in the power tool chuck and prevents slipping.
●Easy to Drill:Step drill HSS cone drill The spiral groove with two slots prevents slipping, quickly removes chips and debones the hole, the pressure is low, the drilling and cutting is faster and more smooth. This allows for faster, more stable and even cutting. The hole can be automatically beveled to clean the drill.
●Long service life and comfortable use: thanks to high-speed steel, the step drill can be used for a long time by heat treatment and tempering. The step drill can easily cut multiple hole sizes with one drill without constantly changing the drill.
●Usage: Taper drill bit suitable for DIY and general construction monitoring / project use. Widely used for cutting various materials such as wood, plastic, thin iron plate, thin aluminum plate and so on. It is suitable for workpieces with a hardness below 25° such as carbon steel with a plate thickness below 5 mm.
●HSS spiral groove step drill set: step cone drill bits are made of high-speed steel, a titanium nitride coating can reduce friction heat and the operating temperature is low, strong and durable. The titanium coating ensures free cutting of steel, aluminium plates, brass, copper, plastic, wood, etc.
Description
HSS step drill
Titanium coating: High quality HSS steel and titanium coated high speed steel extend the service life. Ensures easy cutting, is extremely durable, reduces friction and heat and is characterised by heat resistance, corrosion resistance and rust protection. Unique 2-slot design: The two-slot design also makes it easier to escape material particles and makes the drilling process cleaner. The 118 degree fork tip provides a faster cutting speed and prevents slipping. Acceleration speed. Acceleration: The four flat shafts ensure fast, each step is clearly marked with the depth diameter. The required size can be easily determined by comparing the laser engraving size in the groove of the step drillWide application: Widely used for cutting holes in various materials such as thin iron, thin aluminium, plastic and PVC panels and are suitable for workpieces with a hardness below 25°. As with carbon steel, the thickness of the plate is less than 5 mm

Improved hex shankUnlike the round and triangular shafts on the market, our upgraded hex shank prevents slipping more effectively and sits more securely in any lining, ensuring maximum power transmission. |
Laser engraving technology, thickened titanium coatingWe use a gold plated titanium coating. The precise laser marking on each drill ensures a high level of comfort and is therefore ideal for drilling the required diameter holes clearly and without fading in metals and plastics. |
Fast chip removal for efficient material useDouble straight groove design, large chip removal space and even chip removal angle. More effective in removing chips than spiral grooves, not clogging and more efficient in using materials. |
Three in one function saves time and effortNo more drill changes, a single drill can drill, grate, clean and deburr in one step. No more worries. |

Step Drill Bit Set
Compatible models, bench drill, hand drill, rechargeable drill. Tapered is suitable for drilling larger and deeper holes or for expanding the opening in areas where it has been drilled. The cutting blade design allows faster cutting and automatic deburring of the holes when drilling. Use twist drill: Pre-drilling by gradual drilling, reduce damage to the drill part during drilling. CNC machine tools, each process is strictly controlled and every step of quality control. Compared to the twist drill, the step drill is not easy to break and can cut different sized holes.
Note:
When using an electric drill, be sure to wear protective glasses, masks and gloves. Do not touch it with your hand, as the drill generates heat during use and there is a risk of burning. When using gun drills and bench drills, injecting and cooling water during work can effectively extend the life of the drill. The recommended drilling speed is 250-400 rpm.
