Σετ τρυπανιών Bosch Expert HEX-9, 7 τεμ., Μεγέθη 4–12 mm, Στέλεχος HEX-9

Bosch Expert HEX-9 drill bit set includes seven commonly used diameters from 4 mm to 12 mm, each with a HEX-9 shank for fast, secure mounting in compatible impact drivers and drills. The set is designed for general drilling tasks in wood and other common construction materials, offering a compact selection that reduces the need to carry multiple loose bits. The HEX-9 shank improves torque transfer and reduces slippage in quick-change chucks that accept this profile.

Advantages

The set delivers a practical range of sizes for everyday drilling, with HEX-9 shanks that enable quick changes and reliable retention in compatible tool holders. Hardened steel construction provides consistent drilling performance for general-purpose jobs, while the compact organizer keeps bits sorted and accessible. The uniform shank profile simplifies compatibility with drivers and chucks designed for HEX-9 fittings.

Suitable for

• Drilling holes in soft and medium-density wood
• General carpentry and joinery tasks
• Construction and renovation where common diameters are required
• Quick bit changes in cordless drivers and impact tools with HEX-9 receptacles

Key specifications

• Quantity: 7 drill bits
• Diameter range: 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 10 mm, 12 mm

How to use

Select the required diameter and insert the HEX-9 shank into a compatible quick-change chuck or driver. Ensure the tool is powered off when changing bits, then secure the bit in the holder according to the tool manufacturer’s instructions. Use appropriate speed and pressure for the material being drilled; lower speeds and steady pressure are generally suitable for larger diameters and harder workpieces. After use, return the bits to the organizer to prevent loss and protect the cutting edges.

Recommendations

For best results, match drill speed and feed rate to the material and bit size, clamp workpieces securely, and wear appropriate eye protection. Avoid using these general-purpose bits in hardened steel or masonry without verifying suitability for the material and tool.
