Drill bit set Bosch 2608833827 — 5-piece HSS straight-shank set

Bosch 2608833827 — 5-piece HSS straight-shank set contains high-speed steel twist drill bits in common sizes for general-purpose metal and wood drilling. The set includes five straight-shank drills designed to fit standard chucks and hand drills, providing reliable cutting performance and durability for everyday workshop and on-site tasks. The compact case and balanced selection of sizes make the set convenient to store and carry between jobs.

Advantages

The HSS material delivers good heat resistance and edge retention during drilling into metal and wood. Straight (cylindrical) shanks ensure compatibility with a wide range of drill chucks and reduce the need for adapters. The precision-ground flutes provide consistent chip removal and stable drilling behaviour, while the compact five-piece assortment covers frequently used diameters for repair, installation and maintenance tasks.

Suitable for

• Drilling mild steel, sheet metal and non-hardened metal components
• General wood drilling in construction and joinery
• Routine workshop and maintenance jobs with handheld or benchtop drills
• On-site repair and installation work requiring a small, portable drill set

Key specifications

• Material: high-speed steel (HSS)
• Shank type: straight (cylindrical) shank for standard chucks
• Number of pieces: 5 drill bits
• Application: metal and wood drilling
• Flute design: twist flute for chip evacuation

How to use

Select the drill bit size appropriate for the hole diameter required and secure it in the drill chuck, ensuring the straight shank is seated and tightened. When drilling metal, use a suitable cutting lubricant and start at low speed to establish the center; increase speed moderately once the bit is cutting steadily. For wood, use appropriate speed and feed to avoid splintering. Apply steady, even pressure and withdraw occasionally to clear chips for longer holes. After use, clean the bits and store them in their case to protect cutting edges and maintain performance.

Recommendations

For best results, match drill speed and feed to the material being drilled: lower speeds for thicker or harder metals, higher speeds for softer metals and wood. Use cutting fluid on metal to extend tool life, and inspect bits for wear before precision drilling.
