Bosch Professional Core Drill Bits & Adaptors

Bosch Professional Core Drill Bits & Adaptors at Tooled-Up.com

Bosch Professional Core Drill Bits & Adaptors are built for cutting large-diameter holes through masonry, brick, block and concrete, where a standard drill bit won't do the job. A core bit removes a cylinder of material rather than grinding out the whole hole. That makes it the usual choice for pipe, duct and cable penetrations.

Tooled-Up.com stocks the Bosch Professional selection in four product groups: core drill bits, pilot core drill bits, core drill adaptors and core drill extensions. Together they let you build a setup around the material, hole size and depth of the job in hand.

Because each part does a different job, it pays to choose the bit, adaptor and any extension as a system. Check the specification on each product page to confirm diameter, thread and drill compatibility before you order.

Key Features of Bosch Professional Core Drill Bits & Adaptors

• Core drill bits: Cut a clean, round hole in one pass, leaving less material to remove than a solid-drilled hole of the same size.
• Pilot core drill bits: Include a centring pilot that helps start the cut accurately and stops the bit wandering on the surface.
• Core drill adaptors: Connect the core bit to your drill or rotary hammer, so you can use the machine you already own.
• Core drill extensions: Add reach for deeper holes, such as thick walls and floor slabs, without buying a longer bit.
• Modular approach: Bits, adaptors and extensions can be mixed and matched, so one adaptor can serve several bit diameters.
• Professional build: Designed for repeated use on site, with tough connections that transfer power from machine to bit.

Who Uses Bosch Professional Core Drill Bits & Adaptors?

Anyone who regularly needs a clean, large hole through a solid structure will find a use for these products:

• HVAC installers: Holes for extraction ducts, ventilation and air conditioning pipework.
• Builders and groundworkers: Service entries and drainage runs through blockwork and concrete.
• Refurbishment and maintenance teams: Adding new services to existing buildings with minimal disruption.

Popular Bosch Professional Core Drill Bits & Adaptors

Core Drill Bits

The main cutting tool for round openings in masonry and concrete. Choose the diameter to suit the pipe or duct, allowing a little clearance for sleeves, insulation or fire-stopping.

Pilot Core Drill Bits

A good option when accurate positioning matters, particularly on smooth surfaces or when drilling by hand. The pilot keeps the cut where you marked it.

Core Drill Adaptors

These match your core bit's thread to your machine's chuck or fitting. Check both the bit thread and the drill type before buying.

Core Drill Extensions

Extensions let you drill through thicker walls and slabs. They suit jobs where the bit alone would not reach all the way through.

Frequently Asked Questions

How do I choose the right size core bit?

Start with the outside diameter of the pipe, duct or sleeve passing through the hole, then allow extra clearance for insulation, sealant or fire-stopping. Always check the product specification for the exact cutting diameter.

Do I need an adaptor to use a core bit?

Usually, yes. The adaptor links the core bit's thread to your drill or rotary hammer fitting. Browse the Bosch Professional adaptors at Tooled-Up.com and match the thread and shank type listed on the product page to your equipment.

When should I use an extension?

Use an extension when the wall or slab is thicker than the working depth of the core bit. Extensions also let you clear debris and keep the machine at a comfortable working distance.

What safety checks should I make before core drilling?

Scan for hidden pipes and cables first, and secure the drill and workpiece. Wear eye protection, hearing protection and a dust mask, in line with HSE guidance. If you are using wet drilling equipment on a 240v supply, protect it with an RCD.
