Key benefits of using SDS plus drill bit 14x450mm
When working with concrete and masonry, two key features are key: feed rate and tool durability. This drill bit has been developed with maximum productivity in mind:

Exceptional durability and long service life: The drill bit is made of premium steel that is resistant to high loads, torsion and overheating during intensive operation.
Superior cutting power with Widia insert: The drill tip is equipped with a carbide tip (Widia insert) that easily penetrates the hardest materials, including reinforcing iron in concrete.
Deep drilling length: With a total length of 450 mm and a diameter of 14 mm, this drill bit is ideal for wall penetrations, deep anchoring and routing pipes and cables through thick walls.
Efficient dust removal: The specially designed spiral allows for rapid removal of dust and material from the borehole, which reduces friction, prevents jamming and extends the life of the drill bit.
Universal SDS-Plus system: Quick change without the use of additional tools saves you valuable time on the construction site.

Versatile use in renovation and construction work
The SDS plus drill bit 14x450mm is indispensable for a wide range of construction and craft work. Due to its length and robustness, it is an excellent choice for:

Electrical installations: Drilling passages for electrical cables, protective pipes and boxes through load-bearing walls.
Mechanical installations: Preparation of openings for water pipes, heating systems and air conditioning units.
Installation work: Drilling deep holes for heavy anchors, threaded rods and metal structures.
General construction work: Penetrations of brick and concrete walls during renovations of residential or industrial buildings.

Thanks to the Widia insert, the drill bit maintains its sharpness even after many holes have been drilled, which means less strenuous work for you and less strain on your drilling machine.
Frequently Asked Questions (FAQ) about the product
1. Is this drill bit suitable for drilling into reinforced concrete?
Yes, the SDS plus drill bit 14x450mm is equipped with a high-quality Widia insert (carbide), which is designed to successfully overcome hard obstacles, including reinforced concrete and reinforcing mesh.
2. Which drills is this bit compatible with?
The drill bit uses the standard SDS-Plus clamping system. It is compatible with all rotary hammers and impact drills that support SDS-Plus clamping, regardless of the brand of the device.
3. How to ensure the longest possible service life of the drill bit during work?
For optimal life, we recommend that you do not press too hard on the machine while drilling – let the impact power of the drill do the work. When drilling very deep holes, pull the drill out occasionally to facilitate dust removal from the borehole, which prevents the Widia tip from overheating.

Instructions for using the product:
• Before use, check the SDS+ drill bit 14 × 450 mm to make sure it is not bent, cracked or damaged.
• Insert the drill bit into a compatible SDS+ drill or hammer drill and check that it is properly engaged.
• Mark the drilling location and check that there are no hidden electrical cables, pipes or other installations in the wall.
• Hold the tool with both hands and position the drill bit as perpendicular to the surface as possible.
• Start drilling with moderate pressure. Let the tool do the work without applying excessive pressure.
• When drilling deep, pull the drill bit out occasionally to remove dust and allow it to cool.
• If the drill bit jams, vibrates excessively or overheats, stop working immediately.
• After finishing work, switch off the tool and wait until the drill bit has come to a complete stop.
• Wait for the drill bit to cool before removing it, then clean and store it.

Useful tips for work:
• The drill has a diameter of 14 mm and a length of 450 mm, so it is also suitable for making deeper holes.
• SDS+ chuck allows quick accessory changes without a classic chuck.
• It is particularly suitable for concrete, brick, stone and masonry materials, if its design is intended for these materials.
• With a long drill bit, it is important to start drilling accurately and guide the tool steadily.
• For deep holes, periodically pull out the drill bit to remove the drilled material.
• For longer life, use appropriate pressure and avoid unnecessary overheating.
• Before drilling a large number of holes, check the condition of the cutting tip and spiral flutes.

Warnings:
• CAUTION – a long drill bit can cause strong kickback if it gets stuck.
• Always wear safety glasses, hearing protection, protective gloves and appropriate respiratory protection.
• Before drilling, check for hidden cables, pipes and other installations.
• Do not touch the drill bit immediately after use, as it may be very hot.
• Before changing or removing the drill bit, turn off the tool and disconnect it from the power source or remove the battery.
• Do not use a damaged, bent or severely worn drill bit.
• Be careful not to let particles and dust fly away when working.
• Hold the tool steadily with both hands while drilling.
• Store the drill in a dry place and out of the reach of children.

Same summary

The SDS plus drill bit 14x450 mm is intended for those who often drill deep or long holes in hard materials such as concrete or stone. Due to its larger diameter and length, it is particularly useful for more demanding tasks on a construction site or larger home projects where precise reach is at the forefront. It is suitable for users who already have experience with power tools with an SDS plus clamping system, while it is not the most optimal choice for basic and shorter tasks or thinner materials. Choosing the right tool is particularly important, as too long a drill bit can reduce drilling accuracy in the event of errors.

Answers to frequently asked questions

Is the SDS plus 14x450 mm drill bit compatible with all drills?

This drill bit is only suitable for power tools with SDS plus system. Before purchasing, please check if your drill supports this clamping method, as other chucks are not compatible.

What materials is this drill bit suitable for?

It is best suited for drilling into concrete, masonry or natural stone. For wood, metal or other softer materials, it is better to choose specialized drill bits.

When does it make sense to choose a drill bit of this length?

Such a long drill bit is useful for deep holes, such as when installing cables through thick walls or installing larger anchors. For basic tasks, a shorter drill bit is often sufficient, as the work is more precise and easier.

What does the “over 13 mm” marking mean on this drill bit?

The designation refers to the diameter of the drill bit. This means that it is suitable for drilling larger holes and is generally not intended for fine assembly work or small bores.

What to do if the drill bit does not advance when drilling into hard material?

In case of poor performance, check that the drill bit is still sharp and that you are using a suitable impact tool. It is also not recommended to apply excessive pressure to the tool - let the machine do most of the work.
