Key Features of Sealey Core Drill Bits

Sealey core drill bits incorporate several design features that enhance performance and longevity. High-grade diamond or tungsten carbide segments provide aggressive cutting action through brick, concrete, and stone whilst maintaining dimensional accuracy throughout the drilling process. The segment configuration is optimised to balance cutting speed with tool life, ensuring consistent performance across the bit's working life.

Many Sealey core drill bits feature laser-welded segment attachment, creating exceptionally strong bonds that resist detachment even under demanding conditions. This construction method also allows the bits to withstand higher operating temperatures without degradation, making them suitable for use with both wet and dry drilling applications depending on the specific model.

The shaft designs accommodate various drilling systems, with options including standard SDS-plus fitments for rotary hammer drills and threaded connections for professional core drilling rigs. Centre pilot drills on appropriate models ensure accurate hole positioning and prevent wandering during initial contact with the work surface. Segment geometry incorporates efficient debris clearance channels that prevent binding and promote smoother drilling action.

Popular Sealey Core Drill Bits

The Sealey core drilling range at Tooled-Up encompasses various diameter options to suit different installation requirements. Smaller diameter bits in the 25mm to 50mm range are ideal for electrical back boxes, smaller pipework penetrations, and fixing installations. Mid-range diameters from 60mm to 100mm suit standard plumbing applications, ventilation grilles, and general contractor use.

Larger diameter Sealey core drill bits spanning 110mm to 150mm and beyond cater to drainage installations, large-bore pipework, and substantial ventilation requirements. Professional-grade sets containing multiple commonly-used diameters provide excellent value for tradespeople requiring versatile drilling capabilities across various projects.

Wet and dry variants offer flexibility depending on the application environment and available equipment. Wet-use core drill bits are designed for use with water-cooled core drilling rigs, whilst dry-use models suit handheld power tools where water supply isn't practical or permitted.

Safety and Compliance

When using Sealey core drill bits, adherence to Health and Safety Executive (HSE) guidelines is essential. Always wear appropriate personal protective equipment including safety glasses, hearing protection, dust masks (particularly for dry drilling), and sturdy work gloves. Ensure workpieces are properly secured and check for hidden services before drilling to avoid striking electrical cables, gas pipes, or water mains.

For 240V electrically-powered drilling equipment, verify that tools are PAT tested and in good working condition. Use residual current devices (RCDs) when working in damp conditions or outdoors to protect against electric shock. When operating core drilling rigs, ensure stable mounting and follow manufacturer's torque recommendations to prevent tool binding or kickback.

Comply with Control of Substances Hazardous to Health (COSHH) regulations when dry drilling, as silica dust from masonry materials poses serious respiratory hazards. Where possible, use wet drilling methods or dust extraction systems to minimise airborne particles. Sealey core drill bits should be operated at manufacturer-recommended speeds and fed at appropriate rates to prevent overheating and premature wear.

Frequently Asked Questions

What materials can Sealey core drill bits cut through?

Sealey core drill bits are designed for drilling brick, concrete, stone, masonry, and similar dense materials. Different models suit different applications, with diamond-segment bits excelling in reinforced concrete and extremely hard materials, whilst carbide-tipped variants work effectively in standard masonry and brick. Always select the appropriate bit specification for your material type.

Can I use Sealey core drill bits with a standard power drill?

Smaller diameter Sealey core drill bits with SDS-plus fitments are suitable for use with rotary hammer drills operating in hammer-drill mode. However, larger diameter bits require dedicated core drilling rigs or powerful rotary hammer drills with sufficient torque capacity. Standard power drills generally lack the necessary power and chuck strength for effective core drilling.

Should I use water when drilling with Sealey core drill bits?

This depends on the specific bit type. Wet-use core drill bits require water cooling to prevent overheating and extend cutting life, particularly for larger diameters and dense materials. Dry-use bits are formulated for handheld drilling where water isn't practical, though they may have shorter service life. Check the bit specifications and use the appropriate cooling method.

How do I prevent Sealey core drill bits from binding in the hole?

Apply steady, moderate pressure without forcing the bit. Allow the segments to cut at their designed rate rather than pushing aggressively. Periodically withdraw the bit to clear debris from the cutting path. Ensure your drilling equipment provides sufficient torque and that the bit rotates at the recommended speed for the diameter and material being drilled.

What's the typical lifespan of Sealey core drill bits?

Lifespan varies considerably depending on the materials being drilled, operating conditions, and maintenance practices. Diamond-segment bits drilling standard concrete might achieve 10-30 metres of cumulative drilling depth, whilst harder materials or improper technique significantly reduce this. Regular inspection for segment wear, proper cooling, and avoiding excessive pressure all maximise bit longevity.
