Drill bit set Proline 90003 — 3 pieces, general-purpose drill bits

Proline 90003 — 3 pieces, general-purpose drill bits is a compact set of three drill bits intended for general drilling tasks with hand drills and drill drivers. The set supports basic drilling operations in wood, plastics and other soft materials for household and light professional use. These bits feature a specially shaped solid carbide insert that improves durability and drilling accuracy, and they are also suitable for drilling in masonry, concrete, granite and other natural stones.

Advantages

The solid carbide insert ensures increased wear resistance and long service life while delivering accurate, centered drilling and reduced load on the drill. A three-piece configuration provides coverage for a range of common hole sizes without requiring a large storage set. Compatibility with hand drills and drill drivers allows straightforward use for both DIY home tasks and light professional jobs.

Suitable for

• Drilling in wood and plastic for furniture assembly and repairs
• Light construction tasks in masonry and concrete
• Drilling in granite and other natural stone for small installations
• General household maintenance and DIY projects

Key specifications

• Set contents: 3 drill bits
• Intended use: general-purpose drilling for household and light professional applications
• Shank type: compatible with standard hand drills and drill drivers
• Cutting material: solid carbide insert for improved durability and accuracy
• Suitable materials: wood, plastics, masonry, concrete, granite and other natural stones

How to use

Install the appropriate bit into the drill chuck and tighten securely before starting. Select a drilling speed and feed pressure appropriate for the material: lower speeds for masonry and stone, moderate speeds for wood and plastics. Use steady pressure and allow the carbide insert to do the cutting; avoid excessive force that could cause bit breakage. For masonry or concrete, start with a small pilot hole if required and clear dust from the hole periodically to maintain drilling efficiency.

Usage recommendations

For best results when drilling masonry, concrete or stone, use a hammer drill mode if available and wear suitable personal protective equipment such as safety glasses and dust mask. When drilling wood or plastic, clamp the workpiece to prevent movement and choose an appropriate speed to minimize splintering.
