SDS+ concrete drill bit 6x210 cross point (4 nibs) – The ultimate drill bit for reinforced concrete and masonry
Are you looking for a reliable, extremely precise and durable tool for drilling into the hardest construction materials? The SDS+ 6x210 concrete drill bit with cross-tip and 4 flutes (SKU: 706469) is a top professional tool designed for fast, stable and efficient impact drilling. Whether you are dealing with classic concrete, brick or extremely demanding reinforced concrete, this drill bit ensures superior results without jamming.
Thanks to the advanced geometry with four blades (4 feathers) and the innovative cross-tip made of high-quality VK8 carbide, the drill easily overcomes obstacles such as steel reinforcement in concrete. The length of 210 mm and the diameter of 6 mm are ideal for creating deep and precise holes for anchors, inserts and fixtures.

Why choose an SDS+ cross-tip concrete drill bit?
Classic two-blade drill bits often bend, get damaged or get completely stuck when they come into contact with rebar. Our 4-flute SDS+ drill bit solves this problem with an innovative design that distributes the impact force evenly. This not only extends the life of the drill bit itself, but also protects your rotary hammer from overloading.
The drill bit is made of robust 40X steel, which provides high resistance to bending and torsional loads, while also efficiently removing dust from the borehole thanks to the optimized four-stage spiral.

Key features and technical specifications
This professional drill is distinguished by top-quality materials and a well-thought-out design, adapted for intensive daily use:

VK8 cross carbide plate: The special BK8 alloy on the tip of the drill prevents damage and sinkage when hitting rebar and enables smooth penetration of steel.
Four cutting nibs (4 nibs): Ensure a perfectly round hole, more precise tool guidance in the bore and prevent dangerous jamming.
SDS Plus quick clamping: The standardized clamping system allows for quick, safe and easy bit changes without the use of additional tools.
High-quality 40X steel: The drill body is made of durable steel that perfectly withstands high temperatures and strong impacts.
Efficient dust extraction: Four spirals enable rapid removal of dust and material from the borehole, reducing friction and heating.
Dimensions: The drill diameter is 6 mm, the total length is 210 mm, and the working length is 160 mm.
Packaging and transport dimensions: The packaging length is 55 mm, width 35 mm and height 10 mm.

Benefits of using a 4-point drill bit in your work
Using a professional tool makes a noticeable difference in every project. By choosing this drill bit, you will get the following benefits:

Maximum productivity: Faster drilling means less time and energy spent on the job.
Extreme precision: Thanks to the four blades, the drill bit does not twist, which means your holes will be exactly where you marked them and perfectly round.
Long service life: The VK8 carbide hardness ensures that the drill bit remains sharp even after numerous drillings in the hardest concrete.
Safety at work: Since the drill does not block upon contact with the reinforcement, the risk of kickback (which can injure the user's wrist) is drastically reduced.

Frequently Asked Questions (FAQ)
1. Is this drill bit suitable for regular drills without SDS chuck?
No, this drill bit is equipped with a standard SDS Plus chuck, which is intended for use in hammer drills with this specific quick-clamping system. This drill bit is not suitable for classic drills with a keyless chuck.
2. How does a drill behave when it hits metal reinforcement in concrete?
Thanks to the VK8 carbide cross tip and four cutting edges, the drill does not block when it comes into contact with the reinforcement. Instead, it distributes the impact force evenly, preventing jamming and allowing you to continue drilling without damaging the tool.
3. What materials is this drill bit best suited for?
The drill is particularly suitable for processing hard building materials such as reinforced concrete, classic concrete, brick, masonry, natural stone and other silicate materials.

Instructions for using the product:
Simply attach the drill bit to a tool that supports the SDS system and use it to process concrete and other hard materials. We recommend that you clean the drill bit regularly during processing to ensure accuracy and efficiency in processing. The drill bit is intended for use in various activities, but its durability and resistance may vary depending on the thickness and hardness of the materials.

Useful tips for work:
• Before drilling, check that you have the correct drill bit size for your needs.
• When drilling into concrete and brick, use appropriate speed and pressure to prevent damage to the drill bit and ensure drilling accuracy.
• Use a drill guide to ensure stability and accuracy.
• Clean the drill bit regularly and store it in a dry place, away from moisture and other elements that could damage the drill bit.
• When drilling in tight spaces, use a shorter drill bit to ensure greater accuracy and reduce the risk of injury.

Warnings:
• Use safety glasses, hearing protection and a dust mask.
• Do not touch the drill bit immediately after drilling – it may be very hot.
• Do not use a damaged or worn drill bit.

Same summary

The SDS+ concrete drill bit with a cross-tip and four flutes is suitable for users who frequently drill into harder materials such as concrete or stone and need greater precision and reliability for home repairs or small craft projects. The four-blade design ensures more stable drilling and less chance of jamming in the material. It is worth noting that the drill bit is specialized mainly for mineral materials, so it is not the best choice for wood or metal and is not a universal solution for all tasks. It works well in combination with a suitable impact power tool and is a sensible choice when greater drilling depth is required in hard substrates.
