4-piece SDS MAX drill bit set 600mm with cross tip (16-22mm) and adapter - Professional equipment for demanding drilling in concrete and masonry
Are you looking for a truly reliable and professional solution for demanding drilling in the hardest construction materials, such as concrete, reinforced concrete or brick? The 4-piece SDS MAX 600 mm cross-tip drill bit set (16-22mm) is a premium tool set that was designed with builders, craftsmen and all demanding DIYers in mind. This exceptional set combines three extremely long and durable drill bits and an extremely practical adapter that allows you maximum flexibility when working with different rotary hammers on every construction site.
Thanks to innovative manufacturing technology and advanced head geometry, these drill bits easily overcome the toughest obstacles, including steel reinforcement in concrete. The 600 mm length allows for deep drilling and piercing of extremely thick walls without unnecessary effort, significantly reducing working time and increasing your productivity.
Why is this SDS MAX drill bit set indispensable on the construction site?
In construction and renovation work, speed of execution and reliability of equipment are crucial. Standard drill bits are often damaged, twisted or simply stuck when they come into contact with reinforcement in concrete, which causes loss of time and additional costs. This professional set effectively solves this problem with a new carbide head geometry that ensures even force distribution and prevents the drill bit from blocking when in contact with iron. The result is faster progress through the material, significantly less vibration transmitted to the user, and a noticeably longer tool life.
In addition to the three premium drill bits, the set also includes an SDS-MAX to SDS-PLUS adapter. This is an extremely practical addition that allows you to immediately use your existing drill bits and chisels with SDS-PLUS connection on more powerful and heavier rotary hammers that use SDS-MAX connection. This saves you money on buying additional tools and at the same time reduces the weight of the equipment you have to carry with you into the field.
Key features and benefits that convince

New carbide head geometry: The specially designed cross tip (4 blades) enables extremely precise centering without slipping and efficient drilling, even directly into reinforced concrete.
Exceptional 600 mm length: This length is ideal for making deep openings, penetrating external walls and easily routing installations such as plumbing, electricity, telecommunications and heating.
Set of 3 drill bits of the most sought-after dimensions: Includes the most popular and frequently used diameters for construction and installation work: 16 mm, 20 mm and 22 mm.
Included SDS-MAX to SDS-PLUS adapter: Significantly increases the versatility of your equipment and allows you to use lighter drill bits on heavy machines without the need to purchase a new power tool.
Durable and robust SDS-MAX chuck: Ensures optimal and direct power transfer from the rotary hammer to the drill tip without unwanted slippage or energy loss.

Practical application and maximum efficiency
The drill bits in this set are designed for use with heavy-duty rotary and demolition hammers that use the standard SDS-MAX shank. With an exceptional total length of 600 mm, these drill bits are ideal for breaking through external walls, making pipe and cable passages and anchoring heavy structures into deep concrete foundations. The new, optimized blade geometry ensures that dust, debris and dust particles are quickly and efficiently removed from the borehole through the spiral grooves. This drastically reduces friction, prevents the drill bit from overheating and prolongs its sharpness even during continuous use.
With this set, you'll be ready for any challenge on the construction site. Whether you're breaking through an old stone wall, drilling into a reinforced concrete slab, or paving the way for new installations, this drill bit set with adapter will get the job done quickly, safely, and with extreme precision.
Frequently Asked Questions (FAQ)
Can I drill directly into rebar (iron in concrete) with these drill bits?
Yes, the new geometry of the four-blade carbide crosshead is specifically designed to withstand contact with reinforced concrete. However, to ensure maximum drill life, we recommend moderate and even pressure when directly contacting the steel bar to prevent the blades from overheating.
What exactly does the included adapter in the kit enable?
The included adapter allows you to easily and safely attach smaller drill bits or chisels with SDS-PLUS shank to your heavy-duty SDS-MAX hammer drill. This gives you great flexibility on the jobsite, as you don't have to change the entire machine for smaller jobs, just insert the adapter.
What materials are these drill bits best suited for?
Drill bits are primarily intended for impact drilling in hard construction materials. They are extremely effective when working with concrete, reinforced concrete, solid brick, natural stone, clinker, masonry and other silicate and mineral materials.

Useful tips for work:
• Choose a drill bit of the appropriate diameter depending on the purpose of the work.
• Use appropriate speed and pressure when drilling.
• Clean the drill bit regularly and check its wear.
• When drilling deeper, occasionally pull out the drill bit to remove dust and material debris.
• Store drill bits in a dry and protected area.

Warnings:
⚠️ Drill bits are intended for use with SDS MAX tools.
⚠️ Use safety glasses, gloves and hearing protection when working.
⚠️ Do not touch the drill bit immediately after drilling, as it can be very hot.
⚠️ Before changing the drill bit, turn off the tool and unplug it from the power source or remove the battery.

Same summary

The 4-piece SDS MAX drill bit set with a length of 600 mm and diameters of 16-22 mm is intended for users who frequently drill into harder materials such as concrete or masonry. The set is particularly suitable for DIYers, contractors or those who need different drill bit dimensions for various projects in the house, garden or when adapting. The cross-shaped tip and different sizes make it versatile, but a more specialized user who regularly works with very soft or extremely specific materials may in some cases look for more narrowly focused drill bits. The set offers a good balance between versatility and performance for most domestic and light professional work.
