Proline drill bit set 90005 — 5 pieces

Proline drill bit set 90005 — 5 pieces is a compact collection of masonry drill bits designed for common drilling tasks in building and repair work. The set contains five sizes suitable for creating holes in masonry walls, concrete, granite and other natural stones. These bits are compatible with standard electric drills and hand drills and are intended for users who need a small, versatile selection of bits for household repairs, assembly work and light construction tasks.

Advantages

The drill bits feature a specially shaped solid carbide insert that improves durability and cutting performance, enabling accurate centered drilling and reducing load on the drill. Their geometry and material increase effectiveness when penetrating hard materials while maintaining stable operation. The set’s practical size range and compatibility with standard drill chucks make it easy to switch between tasks without carrying a large assortment of bits.

Suitable for

• Drilling holes in masonry walls and concrete
• Creating openings in granite and other natural stone
• Household repairs and mounting fixtures
• Light construction and renovation tasks
• Use with compatible electric drills and hand drills

Key specifications

• Quantity: 5 drill bits
• Tip material: solid carbide insert
• Intended materials: masonry, concrete, granite, natural stone
• Compatibility: standard drill chucks for electric and hand drills
• Design features: centered drilling geometry to reduce load and improve accuracy

How to use

Secure the appropriate drill bit in the drill chuck and tighten firmly. Select the correct drill speed and, if available, use hammer function for masonry and concrete to increase penetration efficiency. Position the drill perpendicular to the surface and start at low speed to create a guide point, then increase speed gradually while applying steady pressure. Withdraw the bit periodically to clear dust and debris and prevent overheating. After drilling, clean the hole before inserting anchors or fasteners.

Usage recommendations

Use personal protective equipment such as safety glasses, gloves and hearing protection when drilling. For best results in very hard stone or reinforced concrete, use appropriate carbide masonry bits and steady, moderate pressure; avoid excessive force which can damage the bit or the drill. Store the bits in a dry place to prevent corrosion and keep the carbide tips protected from impact.
