Introduction
This manual provides essential information for the safe and effective use of your LENOX Bi-Metal Speed Slot Hole Saw with T3 Technology, 1-3/4-Inch. Please read these instructions thoroughly before operation to ensure proper performance and user safety. This hole saw is designed for cutting various materials, including wood and metal, offering enhanced durability and cutting efficiency.
Safety Information
Always observe the following safety precautions when using the hole saw:
- Wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and hearing protection.
- Ensure the workpiece is securely clamped to prevent movement during cutting.
- Always use the correct arbor for your hole saw size and drill type.
- Do not exceed the maximum recommended RPM for the hole saw and material being cut. Refer to your drill's manual for speed settings.
- Keep hands and loose clothing away from the rotating saw.
- Disconnect the power tool from the power source before changing accessories or performing maintenance.
- Avoid applying excessive force, which can cause the saw to bind or break.
- Clear chips and debris regularly, especially when cutting deep holes, to prevent overheating and binding.
Components
The LENOX Bi-Metal Speed Slot Hole Saw consists of the following primary components:
- Hole Saw Body: The main cylindrical cutting component with teeth.
- Bi-Metal Teeth: Designed for durability and efficient cutting in various materials.
- Speed Slot: A staircase-shaped slot for easy plug ejection.
- Arbor Connection: The threaded base for attaching to a compatible arbor (sold separately).

Setup
Follow these steps to properly set up your hole saw:
- Select the Correct Arbor: Choose an arbor compatible with your hole saw size and power drill. Ensure the pilot drill bit is sharp and securely fastened in the arbor.
- Attach Hole Saw to Arbor: Thread the hole saw onto the arbor until it is hand-tight. Some arbors may require a wrench for final tightening. Ensure it is secure to prevent wobbling during operation.
- Insert Arbor into Drill: Open the chuck of your power drill and insert the arbor shaft. Tighten the chuck firmly to prevent the arbor from slipping.
- Verify Security: Before starting, gently tug on the hole saw to ensure it is securely attached to both the arbor and the drill.

Operating Instructions
Proper operation ensures efficient cutting and extends the life of your hole saw.
General Cutting Procedure:
- Mark the Center: Clearly mark the center point for your desired hole on the workpiece.
- Position the Pilot Bit: Place the pilot drill bit directly on the marked center.
- Start Slowly: Begin drilling at a slow speed to allow the pilot bit to penetrate and the hole saw teeth to engage the material.
- Increase Speed (as appropriate): Once the hole saw is stable and cutting, gradually increase the drill speed. Maintain consistent pressure.
- Clear Chips: For deeper cuts, periodically withdraw the saw to clear chips and allow the saw to cool. This is especially important for metal cutting.
- Complete the Cut: Continue drilling until the hole is fully cut through the material.
Cutting Metal:
When cutting metal, use a lower RPM and apply cutting fluid to reduce heat and extend saw life. The T3 Technology and optimized tooth design are specifically engineered for efficient metal penetration.

Cutting Wood:
For wood, a higher RPM can generally be used. The larger, sharper teeth facilitate fast and efficient cutting through various wood types, including two-by lumber.

Plug Ejection (Speed Slot):
The unique Speed Slot design allows for easy removal of cut material plugs. After completing a cut, use a screwdriver or similar tool to leverage the plug out through the wide staircase slot. This prevents plugs from becoming stuck and speeds up your work.

Maintenance
Regular maintenance ensures optimal performance and longevity of your hole saw.
- Cleaning: After each use, clean the hole saw to remove any accumulated debris, chips, or residue. A wire brush can be effective for cleaning the teeth.
- Inspection: Periodically inspect the teeth for wear, damage, or missing segments. A dull or damaged saw can lead to inefficient cutting and potential safety hazards.
- Lubrication: For metal cutting, ensure adequate lubrication is used during operation.
- Storage: Store the hole saw in a dry place to prevent rust. Consider using a protective case or organizer to prevent damage to the teeth.
Troubleshooting
Refer to this section for common issues and their solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow cutting or excessive heat | Dull teeth, incorrect speed, insufficient lubrication (metal) | Replace saw, adjust drill speed, apply cutting fluid. |
| Hole saw binds or jams | Excessive pressure, chips not clearing, workpiece not secure | Reduce pressure, clear chips, secure workpiece firmly. |
| Plug stuck in saw | Normal occurrence, especially with certain materials | Use a screwdriver through the Speed Slot to eject the plug. |
| Inaccurate cuts | Loose arbor, dull pilot bit, improper starting technique | Tighten arbor, replace pilot bit, start slowly and steadily. |
