1. Product Overview
The LENOX Tools Bi-Metal Speed Slot Arbored Hole Saw with T3 Technology (Model 1772779, 2-Inch/51mm) is engineered for efficient and durable cutting across various materials. This hole saw features an enhanced tooth geometry designed to cut significantly faster than previous LENOX models. Its construction includes thicker walls to minimize tooth loss and improve overall durability, making it twice as durable as previous generations when cutting through metal.
A key innovation is the staircase-designed SPEED SLOT, which provides a wide slot positioned low on the hole saw. This design incorporates multiple leverage points, allowing for easy plug removal with a standard screwdriver. The SPEED SLOT also effectively clears sawdust and chips, preventing plugs from becoming stuck. With a 10% taller design than previous models, this hole saw delivers cleaner cuts, particularly through two-by lumber.

2. Safety Information
Always prioritize safety when operating power tools and accessories. Failure to follow these safety guidelines may result in serious injury or property damage.
- Wear Personal Protective Equipment (PPE): Always wear safety glasses or goggles, hearing protection, and gloves. A dust mask is recommended when cutting wood or other materials that produce fine particles.
- Read Power Tool Manual: Familiarize yourself with the operating instructions and safety warnings of the power drill or tool you are using with the hole saw.
- Secure Workpiece: Always clamp or otherwise secure the material you are cutting to prevent it from moving during operation. Unsecured workpieces can cause kickback or loss of control.
- Inspect Tool Before Use: Before each use, inspect the hole saw and arbor for any damage, dull teeth, or loose components. Do not use damaged tools.
- Proper Installation: Ensure the hole saw is securely attached to the arbor and the arbor is tightly fastened in the drill chuck. A loose connection can cause the saw to wobble or detach.
- Maintain Control: Hold the power tool firmly with both hands. Be prepared for torque reactions, especially when the saw binds or breaks through the material.
- Clear Work Area: Keep your work area clean and well-lit. Remove any obstructions or debris that could interfere with operation.
- Avoid Overheating: For metal cutting, use appropriate cutting fluid or coolant to reduce heat and extend the life of the hole saw. Allow the saw to cool periodically during prolonged use.
- Disconnect Power: Always disconnect the power tool from its power source (unplug or remove battery) before changing accessories, making adjustments, or performing maintenance.
3. Setup Instructions
Proper setup ensures safe and effective operation of your LENOX hole saw.
- Select the Correct Arbor: Ensure you are using an arbor compatible with your LENOX hole saw and your power drill. The LENOX 1772779 hole saw is designed for use with a standard 2-inch arbor fitting.
- Attach Hole Saw to Arbor: Thread the hole saw onto the arbor until it is finger-tight. Some arbors may have a locking mechanism; ensure it is engaged.
- Insert Arbor into Drill Chuck: Open the chuck of your power drill and insert the arbor shank. Ensure the shank is inserted as far as possible into the chuck for maximum grip and stability.
- Tighten Drill Chuck: Securely tighten the drill chuck around the arbor shank. Use a chuck key if your drill requires one, ensuring it is tightened firmly to prevent slippage during operation.
- Verify Stability: Gently pull on the hole saw to confirm it is securely attached to both the arbor and the drill. There should be no wobble or looseness.

4. Operating Instructions
Follow these steps for effective and safe cutting with your LENOX Speed Slot Bi-Metal Hole Saw.
- Mark the Cut Location: Clearly mark the center point where you intend to drill the hole on your workpiece.
- Position the Pilot Bit: Place the pilot bit of the hole saw directly on the marked center point.
- Start Slowly: Begin drilling at a slow speed to allow the pilot bit to penetrate and stabilize the hole saw. Gradually increase speed once the hole saw teeth engage the material.
- Apply Consistent Pressure: Apply steady, consistent pressure. Avoid excessive force, which can cause overheating, premature wear, or kickback. Let the saw's teeth do the work.
- Cutting Metal: When cutting metal, use a lower drill speed and apply cutting fluid to reduce friction and heat. This will prolong the life of the saw and improve cutting efficiency.
- Cutting Wood: For wood, a higher drill speed can be used. The larger, sharper teeth of the LENOX hole saw are designed for fast and efficient cutting in wood.
- Clear Chips: Periodically withdraw the saw from the cut to clear chips and debris, especially in deeper cuts. The Speed Slot design assists in this process.
- Plug Removal (Speed Slot): After completing a cut, the unique Speed Slot design facilitates easy plug removal. Insert a standard screwdriver into the wide slot located low on the hole saw and use the leverage points to eject the plug.

5. Maintenance
Proper maintenance extends the life of your LENOX hole saw and ensures consistent performance.
- Cleaning: After each use, remove any debris, sawdust, or metal shavings from the hole saw and arbor. A brush or compressed air can be used. Ensure the Speed Slot is clear.
- Lubrication (for Metal Cutting): If used for metal cutting, ensure any cutting fluid residue is cleaned off to prevent corrosion.
- Inspection: Regularly inspect the teeth for wear, damage, or dullness. A dull saw will cut inefficiently and can lead to overheating or kickback. Inspect the arbor for bends or damage.
- Storage: Store the hole saw in a dry environment to prevent rust. Keep it in its original packaging or a tool case to protect the teeth from damage.
6. Troubleshooting
Here are solutions to common issues you might encounter:
| Problem | Possible Cause | Solution |
|---|---|---|
| Slow cutting or excessive heat | Dull teeth, incorrect speed, insufficient pressure, no cutting fluid (for metal) | Replace saw if teeth are dull. Adjust drill speed (slower for metal, faster for wood). Apply consistent, firm pressure. Use cutting fluid for metal. |
| Plug stuck in saw | Material buildup, improper plug ejection technique | Use the Speed Slot with a screwdriver to leverage and eject the plug. Ensure the slot is clear of debris. |
| Hole saw wobbles or vibrates excessively | Loose arbor, bent arbor, damaged hole saw, improper chuck tightening | Ensure arbor is tightly secured in drill chuck and to the hole saw. Inspect arbor and saw for damage; replace if bent or damaged. |
| Kickback during operation | Workpiece not secured, excessive force, saw binding | Always clamp or secure the workpiece. Apply steady, controlled pressure. Reduce force if saw binds. |
