Safety Information
Always prioritize safety when operating power tools. Failure to follow these safety guidelines may result in injury or damage to the drill bit or workpiece.
- Wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and hearing protection.
- Ensure the workpiece is securely clamped before drilling to prevent movement.
- Use the correct drill speed for the material being drilled. Refer to your power drill's manual for guidance.
- Apply steady, even pressure. Avoid excessive force, which can cause the drill bit to overheat, break, or bind.
- Allow the drill bit to cool down during prolonged use, especially when drilling hard metals. Use cutting fluid or coolant when recommended.
- Never touch a recently used drill bit, as it may be extremely hot.
- Disconnect the power drill from the power source before changing drill bits or performing maintenance.
- Keep the work area clean and well-lit.
Product Overview
The Fischer 543110 HSS-R DIN338 Metal Drill Bit is designed for drilling into various metals. This set includes 10 drill bits, each measuring 4.7x47/80mm, manufactured from high-quality alloy steel for durability and precision.
Key Features:
- Material: High-Speed Steel (HSS-R) with an alloy steel composition for enhanced strength and wear resistance.
- Standard: Manufactured according to DIN 338, ensuring adherence to specific quality and dimensional standards.
- Shank Type: Straight shank, compatible with most standard drill chucks.
- Cutting Angle: 135-degree split point for improved self-centering and reduced walking on the workpiece.
- Flute Type: Spiral flutes for efficient chip removal during drilling.
- Finish: Steel finish for corrosion resistance.

Setup
Proper setup is crucial for safe and effective drilling.
- Select the Correct Drill Bit: Choose the appropriate diameter drill bit for your application. This set provides 4.7mm diameter bits.
- Prepare the Power Drill: Ensure your power drill is unplugged or its battery is removed before inserting the drill bit.
- Insert the Drill Bit: Open the drill chuck by rotating it counter-clockwise. Insert the straight shank of the Fischer drill bit into the chuck, ensuring it is seated deeply and centrally.
- Secure the Drill Bit: Tighten the drill chuck firmly by rotating it clockwise. For keyless chucks, hand-tighten securely. For keyed chucks, use the chuck key to ensure maximum grip. A loose drill bit can wobble, cause inaccurate holes, or become a projectile.
- Prepare the Workpiece: Mark the drilling location accurately. For metal, use a center punch to create a small indentation at the drilling point to prevent the drill bit from wandering. Secure the workpiece firmly with clamps or a vise.
Operating Instructions
Follow these steps for optimal drilling performance and safety when using the Fischer 543110 HSS-R DIN338 Metal Drill Bit.
- Start Slowly: Begin drilling at a low speed to create a pilot indentation, especially if a center punch was not used. Gradually increase speed once the bit has engaged the material.
- Apply Consistent Pressure: Apply steady, firm pressure directly in line with the drill bit. Avoid excessive side pressure, which can cause the bit to bend or break.
- Manage Heat: Drilling metal generates heat. For prolonged drilling or harder metals, use a cutting fluid or coolant to lubricate the bit and cool the workpiece. This extends bit life and improves cutting efficiency. Periodically withdraw the bit to clear chips and allow cooling.
- Clear Chips: The spiral flutes are designed to remove chips. If chips accumulate, withdraw the drill bit slightly to clear them, then resume drilling.
- Maintain Speed: Maintain a consistent drilling speed. Too slow can cause rubbing and heat buildup, while too fast can dull the bit quickly.
- Breakthrough: As the drill bit approaches breakthrough, reduce pressure to prevent sudden grabbing or splintering of the material.

Maintenance
Proper maintenance extends the life and performance of your drill bits.
- Cleaning: After each use, clean the drill bits to remove metal chips and debris. A stiff brush or compressed air can be used.
- Lubrication/Protection: Apply a light coat of oil to the drill bits after cleaning to prevent rust, especially if they will be stored for an extended period.
- Storage: Store drill bits in their original case or a dedicated drill bit organizer to protect the cutting edges from damage and to prevent loss. Keep them in a dry environment.
- Sharpening: HSS-R drill bits can be sharpened when they become dull. This process requires specialized tools and knowledge to maintain the correct cutting angles. If unsure, consider professional sharpening or replacement.
Troubleshooting
Common issues encountered during drilling and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Drill bit dulls quickly | Incorrect speed, insufficient coolant, excessive pressure, drilling too hard material. | Reduce drilling speed, use cutting fluid, reduce pressure, ensure material is suitable for HSS-R bits. |
| Drill bit breaks | Excessive side pressure, bit binding, incorrect feed rate, worn out bit. | Apply steady, even pressure; ensure workpiece is secure; clear chips regularly; replace worn bits. |
| Hole is not round or accurate | Loose drill bit, wandering bit (no pilot hole/center punch), uneven pressure. | Ensure bit is securely tightened; use a center punch; apply consistent, straight pressure. |
| Excessive smoke or burning smell | Overheating due to high speed or lack of coolant. | Reduce drilling speed, use cutting fluid, allow bit to cool. |
