Drill Bit Set Rebel Tools RB-1122 — HSS metal drill bits, 6 pieces

Rebel Tools RB-1122 is a set of six HSS metal drill bits designed for general-purpose metalworking. The kit contains commonly used metric sizes in high-speed steel to provide heat resistance and wear properties suitable for drilling steel, non-ferrous metals and metal alloys with handheld drills and drill presses. The compact set is intended for repair, assembly and fabrication tasks where reliable cutting performance and straightforward size selection are required.

Advantages

The HSS construction offers good hardness and thermal stability during intermittent and continuous drilling in metal. A selection of six sizes covers frequent workshop and maintenance needs without overloading the tool kit. The bits are compatible with standard drill chucks, allowing use in cordless and corded handheld drills as well as drill presses. The set’s straightforward design focuses on durability and consistent hole quality when used with correct speeds and cutting conditions.

Suitable for

• Drilling holes in mild and alloy steels
• Working with non-ferrous metals such as aluminum and brass
• Maintenance, repair and assembly tasks
• Workshop and on-site metal fabrication

Key specifications

• Material: High-speed steel (HSS)
• Number of pieces: 6
• Intended material: Steel, non-ferrous metals, metal alloys
• Compatibility: Standard drill chucks for handheld drills and drill presses
• Typical use: Through-holes and pilot holes in metalwork

How to use

Secure the chosen drill bit in the drill chuck with proper tightening and set the drill to an appropriate speed for the material being cut. For steel and alloys use slower speeds and steady feed; for softer non-ferrous metals increase speed while avoiding excessive feed pressure. Apply cutting fluid or lubricant when drilling harder steels to reduce heat and improve tool life. Withdraw the bit periodically to clear chips and prevent clogging, and allow the bit to cool during extended drilling sessions.

Usage recommendations

Use appropriate personal protective equipment such as eye protection and gloves. Match drill speed and feed to the workpiece material, use cutting lubricant when needed, and replace worn bits to maintain hole accuracy and safety.
