SDS MAX drill bit 20x600mm with Widia cross tip – Professional performance for the most demanding challenges
Are you looking for an extremely robust and reliable tool for drilling into the hardest construction materials? The SDS MAX drill bit 20x600mm with cross tip Widia (SKU: M14020) is a premium tool designed for professionals and demanding DIYers. With a length of 600 mm and a diameter of 20 mm, this drill bit is an ideal choice for drilling deep holes in reinforced concrete, brick, natural stone and other hard surfaces.
Thanks to the advanced 4-flute Widia plate and the optimized SDS MAX chuck, this drill bit ensures maximum power transfer from the impact hammer directly to the work surface. Forget about jamming and inefficient work - with our drill bit you will complete projects faster, more precisely and with less effort.

Why choose SDS MAX drill bit 20x600mm Widia?
In construction work, two key features are key: speed and tool durability. This drill combines superior metallurgy and sophisticated geometry, which provides a number of advantages over standard drills:

4-blade cross-tip (Widia): The specially designed cross-tip made of extremely hard carbide (Widia) enables precise centering without slipping. The four blades effectively break the material, preventing the drill bit from jamming when it encounters reinforcement or extremely hard rock.
Exceptional length of 600 mm: Ideal for drilling through thick walls, foundations and making penetrations for installations (plumbing, electricity, heating).
High-quality steel: The drill body is made of hardened alloy steel, which is resistant to high torsional loads and prevents the drill from twisting during intensive work.
Universal SDS MAX system: The standardized SDS MAX connection ensures quick changes without the use of additional tools and is compatible with all brands of rotary and demolition hammers that support this system.


Key technical features and specifications
This drill is designed with long-term industrial use in mind. Below are the detailed product specifications:

Drill bit diameter: 20 mm (ideal for medium-sized anchor bolts and pipe penetrations)
Total drill bit length: 600 mm (for deep drilling and breakthroughs)
Clamping system (holder): SDS-MAX (ensures safe and firm clamping)
Blade geometry: Cross tip with 4-edge Widia blade
Suitable materials: Concrete, reinforced concrete, brick, silicate brick, natural stone, masonry


Advantages of use in practice
When working in the field, every minute counts. The SDS MAX drill bit 20x600mm allows you to get the job done without unnecessary interruptions. The special spiral of the drill bit is optimized for quick removal of dust and debris from the borehole. This not only speeds up the drilling process itself, but also reduces friction and overheating of the drill bit, which drastically extends its service life.
Whether you are installing heavy metal structures, performing electrical installations, or renovating an older building with stone walls, this drill will become an indispensable part of your equipment.

Frequently Asked Questions (FAQ)
1. Is this drill bit suitable for drilling into reinforced concrete (iron)?
Yes, the drill bit is equipped with a 4-blade Widia cross-tip, which is designed to withstand contact with rebar in concrete. However, we recommend caution and even pressure when the drill bit encounters the steel bar to extend the life of the blades.
2. Can I use this drill bit on a regular drill with an SDS Plus chuck?
No, this drill bit uses the professional SDS MAX chuck system, which has a larger chuck diameter than SDS Plus. They are only suitable for larger and more powerful hammer drills with an SDS MAX chuck.
3. How to prevent the drill bit from overheating when drilling deep holes (600 mm)?
When drilling deep holes, it is crucial to periodically pull the bit out of the hole (while it is still rotating) to remove any accumulated dust. This reduces friction, prevents the Widia tip from overheating, and ensures faster progress.

• While drilling, check periodically to make sure the drill bit is still properly secured in the hammer.
• After use, clean the drill bit and store it in a dry place to prevent rusting and other damage.

Warnings:
• Do not use a damaged or worn drill bit.
• Wear safety glasses and gloves when working.
• Switch off the power tool before changing the drill bit.
• Be careful of hidden electrical cables and pipes in the material.

Same summary

The SDS MAX drill bit 20x600mm with cross-tip Widia is suitable for users who often drill deeper holes in concrete or stone, especially with more powerful impact drills. Due to its larger diameter and length, it allows you to reach more difficult places and effectively drill into harder materials, where standard drill bits are not sufficient. It is mainly useful for renovation work, larger installations or construction projects in the home and professional environment. For basic, less demanding household tasks or work with light materials, this drill bit may be too bulky or less practical.

Answers to frequently asked questions

Is this drill bit suitable for use with any impact drill?

The SDS MAX drill bit is designed specifically for tools with an SDS MAX shank, so it is not suitable for standard or smaller shanks; always check compatibility with your tool.

What material is best suited for drilling with this drill bit?

The drill bit is optimal for drilling into concrete and stone, where it provides good efficiency and stability even with longer boreholes.

Can I also use this drill bit to drill into wood or metal?

This drill bit is not intended for wood or metal, as its shape and cutting geometry are adapted exclusively for drilling into harder mineral materials.

How can I extend the life of this drill bit?

For a longer service life, use the drill exclusively for the specified materials, clean the tip regularly and avoid excessive pressure during use.

What does the Widia cross tip mean in practice?

The cross-tip allows for more accurate centering and reduces the chance of jamming in the material, while Widia provides additional strength and excellent wear resistance when drilling into concrete or stone.
