VEVOR Diamond Core Drilling Machine, 20-254 mm Drilling Diameter, Stand-Mount Dry and Wet Concrete Core Drill Rig with 10 Bits, 535/920 RPM 2-Speed, UNC1 1/4-7 Thread, for Concrete Brick Stone, 2500W

2500W Motor with Smart Dual Speed Control for Any Project

This diamond core drilling machine features a powerful 2500W motor built for demanding jobs. It has two speed settings, 535 RPM and 920 RPM, so it can drill holes of different sizes and types of materials. With its 1700W no-load input, this machine works quickly and efficiently, and its speed control lets you handle both small precision holes and large-diameter drilling with ease.

The transmission has two speeds: 920 RPM for faster drilling in soft materials and 535 RPM for precise drilling in hard concrete and reinforced structures. The adjustable speeds help extend bit life while maintaining strong cutting performance. The motor specification ensures it will work reliably in tough plumbing, electrical, HVAC, and building projects.

Drill Any Size Hole with 10 Inch Capacity and 19.7 Inch Reach 

It can handle large-bore tasks such as utility penetrations, HVAC installations, and structural changes thanks to its 10-inch (260mm) maximum drilling diameter. The 19.7-inch (500 mm) drilling depth makes it suitable for drilling through thick walls and for deep drilling tasks. The UNC 1-1/4"-7 threaded spindle is compatible with standard diamond core bits that can drill holes from 0.8 inches to 10 inches in diameter.

This drilling capacity works for both concrete and brick, with hole sizes ranging from 0.8 to 10 inches (20 to 254 mm). This makes it useful for a wide range of building projects. The long drilling depth reduces the need to reposition the machine when drilling through thick walls and helps keep the hole straight and accurate. 

Smart Safety Features with Diamond Core Drilling Machine Protection Technology 

The built-in safety clutch releases instantly when the drill bit encounters excessive resistance or becomes stuck, protecting both the operator and the equipment. This system trips when resistance is too high, helping prevent kickback that could cause injury. Both the user and the motor are protected from damage by the automatic disengagement.

After clearing the blockage, the clutch mechanism quickly resets, allowing work to continue without interruption. When drilling through reinforced concrete with embedded rebar or unexpectedly hard materials, this diamond core drilling machine's safety feature is especially useful. 

Clean Drilling with Wet and Dry Options Plus No-Leak Design

Wet and dry drilling options are available on this diamond core drilling machine, enabling it to work effectively in a variety of settings. For indoor work, the wet-drilling option clears debris and cools the bit with a steady water flow. The outside diameter of the barbed fitting water inlet is 0.3 inches (8.6 mm), so it fits standard water supply connections.

The design reduces common leakage points, helping improve reliability during wet drilling. This design helps maintain reliable performance during wet drilling while preventing water from entering critical components. The sealed design helps protect key components during wet drilling, and the cooling system extends bit life and improves cutting performance.

Lightweight Aluminum Construction with 50.7-Pound Portable Stand Design 

Although it is lightweight, the aluminum body is strong and holds up well in harsh work settings. It only takes one person to move and set up the whole machine and stand, which weighs 50.7 pounds (23 kg). The small size (19.3 x 6.2 x 35.2) allows it to fit through normal doorways and into vehicle trunks for easy moving between sites.

The built-in roller wheels and PVC water hose make it easier to move around while still meeting professional standards. The steel output shaft delivers consistent drilling performance thanks to precise manufacturing. The design is light, keeping the structure strong enough for precision drilling while reducing human fatigue during setup and positioning.

Premium Quality with Diamond Core Drilling Machine Professional Standards 

The heavy-duty aluminum alloy frame is strong and light, and it will not rust or wear down in harsh work settings. The solid metal base improves drilling stability and accuracy. During drilling, the thicker guide rail system keeps the bit perfectly aligned.

Crack-resistant PVC water hoses and reinforced mounting hardware are just a few of the parts that reflect quality construction. The materials are industrial-grade, so they can withstand professional use while still meeting the accuracy standards required for precision drilling. 

Works for Any Project - From Pipes to Building Construction 

Some uses for this diamond core drilling machine include roadwork, home remodeling, repairs, and utility installations. It works effectively on stone, marble, brick, and concrete, and other building materials. Electrical conduit routing, water penetrations, HVAC ducts, and structural changes are all common uses.

The flexible design lets you drill in both horizontal and vertical directions, so you can use it for floor openings, wall penetrations, and installations above. Commercial contractors depend on this gear to make precise utility penetrations that protect the structure and leave clean, accurate holes. 

Complete 10-Piece Diamond Bit Set with 156.1-Pound Total Package Weight 

This complete diamond core drilling machine set includes 10 high-quality drill bits for cutting reinforced concrete, brick, marble, and masonry. The drill bits are sized 1", 2", 3", 4", 5", 6", 7", 8", 9", and 10". The full package weighs 156.1 pounds (70.8 kg) and is a practical choice for a wide range of drilling tasks. Each bit has laser-welded segments to make it last longer and cut more consistently.

The bit set that comes with it means you do not have to buy any other bits. It covers a wide range of needs, from small pipe penetrations to big utility openings. The premium bit structure works with materials such as dense brick, natural stone, and reinforced concrete with rebar. This diamond core drilling machine comes fully equipped and ready to use right away.
