1. Introduction
This manual provides essential information for the safe and effective use, maintenance, and storage of the Cleveland CLE-MAX C71006 2001G General Purpose Jobber Length Drill Bit. Please read this manual thoroughly before using the product to ensure optimal performance and user safety.
2. Product Overview
The Cleveland CLE-MAX C71006 2001G is a high-quality jobber length drill bit designed for general-purpose drilling applications. It features a durable HSS-E (High-Speed Steel with Cobalt) construction and a steam oxide finish, enhancing its wear resistance and lubricity. The 118-degree point angle is suitable for a wide range of materials, offering a good balance of strength and sharpness.

3. Setup and Preparation
- Safety First: Always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and hearing protection, when operating drilling machinery.
- Inspect the Drill Bit: Before each use, inspect the drill bit for any signs of damage, such as chips, cracks, or excessive wear. Do not use damaged drill bits.
- Secure the Workpiece: Ensure the material to be drilled is securely clamped to prevent movement during drilling, which can cause breakage or injury.
- Chuck Installation: Insert the drill bit into the drill chuck, ensuring it is seated firmly and centered. Tighten the chuck securely using a chuck key or by hand, depending on the drill type.
- Select Proper Speed: Refer to drilling charts or manufacturer recommendations for the appropriate drilling speed (RPM) based on the material type and drill bit diameter.
4. Operating Instructions
- Pilot Hole (Optional): For larger holes or harder materials, consider drilling a smaller pilot hole first to guide the main drill bit and reduce strain.
- Apply Pressure: Apply steady, consistent pressure to the drill. Avoid excessive force, which can cause the bit to overheat or break.
- Use Coolant/Lubricant: For most metal drilling applications, use a suitable cutting fluid or lubricant to reduce friction, dissipate heat, and extend drill bit life.
- Clear Chips: Periodically retract the drill bit from the hole to clear chips and allow coolant to reach the cutting edge. This prevents chip packing and overheating.
- Maintain Straightness: Ensure the drill is held perpendicular to the workpiece to prevent the drill bit from bending or breaking.
- Finish Drilling: Once the hole is complete, slowly withdraw the drill bit while it is still rotating to prevent burring and ensure a clean exit.
5. Maintenance
- Cleaning: After each use, clean the drill bit to remove any debris, chips, or residue. A wire brush or cloth can be used.
- Lubrication/Protection: Apply a light coat of oil to the drill bit after cleaning, especially if storing for extended periods, to prevent rust and corrosion.
- Storage: Store drill bits in a dry, organized manner, preferably in a drill index or protective case, to prevent damage to the cutting edges and to keep them sharp.
- Sharpening: While HSS-E bits are durable, they can be resharpened by a professional or with appropriate sharpening tools if the cutting edges become dull. Ensure the original point angle (118 degrees) is maintained.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Drill bit breaking | Excessive feed pressure, incorrect speed, lack of coolant, improper clamping, dull bit. | Reduce pressure, adjust speed, use coolant, secure workpiece, sharpen/replace bit. |
| Poor hole quality (rough, oversized) | Dull cutting edges, incorrect speed/feed, excessive vibration, improper point grind. | Sharpen/replace bit, adjust speed/feed, ensure stable setup, check point geometry. |
| Overheating/Smoking | Insufficient coolant, too high RPM, dull bit, chip packing. | Increase coolant flow, reduce RPM, sharpen/replace bit, clear chips frequently. |
| Drill bit "walking" or wandering | No pilot hole, uneven pressure, material hardness variation. | Use a center punch or pilot drill, apply even pressure, consider a different bit for very hard materials. |
