Main features of reduced shank drill bits:

1. Material: The only manufacturer in China who uses DIN materials in batches to increase the carbon, tungsten, and molybdenum content, thus ensuring high carbon saturation and superior material properties.

2. Adopt unique high-speed steel heat treatment technology, such as slow heating, rapid cooling technology, high quenching temperature, and tempering temperature technology, and ox nitridation technology to improve wear resistance and rust resistance.

3. Straight drill below 13mm adopts a fully ground process, which not only has a good finish but also can ensure the radial run-out of the drill bit within 0.03. Drilled holes are more accurate. Similarly, the taper drill uses the outer diameter of the CNC outer circle to ensure that the radial run-out of the taper drill is also within 0.03 mm.

4. The groove shape of the drill bit has combined the shape of the parabolic, which makes the drill bit stronger and the chip removal smoother.

5. Through the technical innovation of high-speed steel twist drill, the life of the drill bit of our factory is generally higher 50% than the mainstream products in the domestic market, reaching the service life of international famous brands.

6. The second generation of hss drill is not only suitable for the processing of general steel such as carbon steel, but also for difficult to machine materials such as die steel and stainless steel.

How to choose the right reduced shank drill bit 8PCS HSS6542 1/2” Reduced Shank Drill Bits Set
The reduced shank primarily solves chuck capacity limitations. When choosing, consider the following:
Required hole diameter
These drill bits are useful when you need a hole larger than a standard 13 mm chuck allows, but you do not want or cannot use a drill bit with a Morse taper shank.
Machine type
They are designed for hand drills, cordless drills, and bench drills equipped with a standard chuck.
If your machine has a Morse taper (MT) spindle, it is more suitable to use drill bits with Morse taper shank (e.g., DIN 345).
Power and stability
A larger diameter means higher torque. The drill must have sufficient power and allow low speed settings. With less powerful cordless tools, drilling larger diameters may be at the limit of their capacity. DIN345 Taper Shank Drill (Hgh-Speed Steel) Cutting Tool Bit
Material being drilled
As with standard DIN 338 length, you can choose between HSS, ground versions, or cobalt versions depending on the hardness of the material.

Where and how reduced shank drill bits are used
They are mainly used for:
installation of steel structures,
drilling holes for larger bolts and threaded rods,
modifying profiles and thicker steel sheets,
service work in the field. DIN345 HSS Morse Taper Shank Twist Drill Bits
They are suitable where a Morse taper machine is not available but a larger hole is required.
Metal drilling must always be performed without hammer action.

How to work with reduced shank drill bits HSS6542 Amber Surface Reduced Shank Twist Drill Bits
When drilling larger diameters, it is necessary to:
work at lower speeds,
hold the drill firmly and steadily,
secure the workpiece firmly,
consider pre-drilling with a smaller bit for larger diameters.
A larger diameter means higher material resistance and greater load on both the tool and the drill bit. It is therefore important to work smoothly and avoid excessive feed pressure.  HSS Morse Taper Shank Drills
