Product Description

KIPMONT Diamond Core Drill Bits are designed for fast, clean drilling in stone, tile and masonry materials. Built with premium vacuum brazed diamond technology, these stone hole saws deliver aggressive cutting performance on hard materials while producing clean, smooth holes with reduced edge chipping.

Made for porcelain tile, ceramic tile, granite, marble, quartz, concrete, engineered stone and masonry, they are ideal for countertop fabrication, faucet holes, pipe holes, electrical pass throughs, tile installation, kitchen and bathroom remodeling, and general construction work. Designed for stone fabricators, countertop installers, tile contractors, plumbers, electricians, contractors, remodelers and serious DIY users, these core bits perform equally well in both shop fabrication and on-site installation.

The thin-wall barrel reduces cutting resistance for faster drilling, smoother control and
improved efficiency. Every size provides a 2-inch drilling depth, making these core bits
suitable for most countertop slabs, vanity tops, tile walls and common stone fabrication
applications. Sizes 3/4 inch and larger feature cooling slots for improved slurry removal and heat dissipation, along with four vacuum brazed side protection segments—two inner and
two outer—to help protect the steel barrel, reduce side friction and produce cleaner, smoother hole walls.

Usage Instructions

➊ Preparation

Tool Installation	Securely mount the KIPMONT core drill bit onto a 5/8”-11 angle grinder before drilling.
Water Supply	Wet drilling is recommended whenever possible to reduce heat, minimize dust and extend tool life.
Safety Gear	Always wear appropriate personal protective equipment, including safety glasses, gloves and a dust mask.

➋ Drilling Process

For the best accuracy, use a drilling guide or template whenever possible.
Clamp a scrap piece of stone beneath the work piece to reduce chipping whenever
possible.
Wet drilling is strongly recommended for better cooling, longer tool life and reduced dust. Ensure steady water supply during operation.
Drilling Depth Guidelines. The maximum drilling depth is 2 inches.
Alternate Tool Use: To use with a standard drill, a separate 5/8"-11 to 3/8" or 1/2" shank adapter is required.
Periodically withdraw the bit during drilling to improve cooling and slurry removal.

➌ Freehand Drilling Tips

Start at about a 45-degree angle to create a shallow groove.
Once the groove is established, gradually bring the bit upright to 90 degrees while
maintaining steady control.
Apply light, steady pressure and let the diamond do the work. Do not force the bit.

Maintenance & Storage

✅ Clean after use: Rinse the bit with water to remove stone debris and slurry.
✅ Dry thoroughly before storage to prevent corrosion.
✅ Inspect the core bit for wear or damage before each use.
✅ Store in a dry place, preferably in original packaging to avoid accidental damage.
✅ Do not store the bit while wet.

Safety Guidelines

Always wear safety glasses, hearing protection, gloves and a dust mask.
Secure the workpiece firmly before drilling.
Keep hands, clothing and body parts away from the rotating bit.
Never exceed the maximum operating speed of 11,000 RPM.
Inspect the core bit before each use. Replace any damaged or excessively worn bit.
Disconnect the power tool before installing, removing or changing the core bit.

How to Use KIPMONT Diamond Core Drill Bits for Stone Drilling

KIPMONT Diamond Core Drill Bits are designed for drilling clean and accurate holes in stone, granite, marble, porcelain, quartz, concrete, and other hard materials. Proper tool selection, water cooling, and drilling technique help achieve better cutting performance and extend the life of the diamond core bit.

Follow these steps for safe and effective drilling.

Step 1: Choose the Correct Core Drill Bit

Select a diamond core drill bit based on the required hole size and drilling material.

KIPMONT Diamond Core Drill Bits are available in multiple diameters for different applications, including countertop fabrication, plumbing openings, faucet holes, and other stone drilling projects.

Before drilling, confirm that the bit size, thread connection, and tool compatibility match your application.

Step 2: Install the Core Drill Bit

Install the diamond core drill bit securely onto a compatible drilling tool.

KIPMONT core drill bits use a standard 5/8"-11 thread, making them compatible with many variable-speed angle grinders, wet polishers, and suitable drilling tools.

Make sure the connection is clean and tight before operation to prevent vibration or uneven drilling.

Step 3: Mark the Drilling Location

Mark the center position of the hole before drilling.

For smooth or polished surfaces, creating a small guide mark or using a drilling guide can help prevent the bit from wandering during startup.

Accurate positioning helps create cleaner holes and reduces surface damage.

Step 4: Start Drilling Slowly

Begin drilling at a low speed with light and steady pressure.

Keep the drill perpendicular to the surface and allow the diamond segments to gradually cut the material.

Do not force the tool or apply excessive pressure, as this can increase heat, reduce drilling efficiency, and shorten tool life.

Step 5: Use Water Cooling During Drilling

Wet drilling is recommended when using diamond core drill bits.

Water helps:

Reduce heat buildup
Flush away drilling debris
Improve cutting efficiency
Extend diamond segment life

Keep the drilling area properly cooled while avoiding excessive water contact with electrical components.

Step 6: Remove the Core Plug

After completing the hole, remove the remaining core material inside the drill bit.

Gently remove the core plug using an appropriate method. Avoid striking the diamond segments directly, as impacts may damage the cutting surface.

Step 7: Clean and Store the Drill Bit

After use, rinse the core drill bit to remove stone slurry and debris.

Dry the tool completely before storage. Keep the thread connection and diamond segments clean to maintain performance for future drilling projects.

Frequently Asked Questions

1. What materials can KIPMONT Diamond Core Drill Bits be used on?

KIPMONT Diamond Core Drill Bits can be used on a variety of hard materials, including granite, marble, quartz, engineered stone, porcelain, concrete, and other masonry materials.

They are commonly used for countertop fabrication, faucet holes, sink installations, plumbing openings, and other stone drilling applications.

2. What tools are compatible with KIPMONT Diamond Core Drill Bits?

KIPMONT Diamond Core Drill Bits feature a standard 5/8"-11 thread and are compatible with many variable-speed angle grinders, wet polishers, and other suitable drilling tools.

Always confirm that your tool supports the correct thread connection and operating speed before use.

3. Should diamond core drilling be done wet or dry?

Wet drilling is recommended whenever possible.

Water helps control heat, remove drilling debris, and extend the life of the diamond segments.

For dry drilling applications, use proper dust control methods and avoid overheating the tool.

4. What speed should I use when drilling with a diamond core bit?

Use a controlled speed appropriate for the material and bit diameter.

Start slowly and apply consistent pressure. Running the bit too fast can generate excessive heat, while insufficient pressure may reduce cutting efficiency.

5. Why is my diamond core bit not cutting effectively?

Several factors can affect drilling performance:

Incorrect bit selection for the material
Excessive drilling speed
Insufficient water cooling
Too little or too much pressure
Diamond segments becoming glazed

Adjusting drilling speed, improving cooling, and allowing the diamonds to cut naturally can help restore performance.

6. How can I extend the life of my diamond core drill bit?

To maximize tool life:

Use the correct drilling speed
Keep the bit properly cooled with water
Avoid excessive pressure
Clean the bit after each use
Store the tool in a dry location

Proper operation and maintenance help maintain consistent drilling performance.

7. What size diamond core drill bit should I choose?

Choose the bit diameter based on the hole size required for your project.

For example, smaller diameters are commonly used for faucet holes and small openings, while larger diameters are used for plumbing, drains, and larger installations.

Always verify the required hole size before drilling.
