Drill bit Bosch 1.5 mm twist 1 pc – model 2 608 585 907

Bosch 1.5 mm twist drill bit, model 2 608 585 907, is a single high-precision carbide or high-speed steel bit designed for accurate drilling of small-diameter holes. Supplied in a blister pack and sold as one piece, the 1.5 mm diameter makes this drill bit suitable for creating pilot holes, precision repairs and delicate hobby tasks in compatible materials. The bit features a standard twist geometry for efficient chip removal and stable drilling performance when used with appropriate speed and clamping.

Advantages

The 1.5 mm twist drill bit offers precise diameter control and clean hole edges, reducing the need for additional reaming. Its standard twist flute design promotes reliable chip evacuation and consistent drilling behavior. Supplied individually in a blister pack, the bit is easy to store and identify. The compact diameter and accurate tip angle enable accurate pilot hole positioning and minimal material splitting when used correctly.

Suitable for

• Drilling pilot holes for screws in wood, plastic and thin metal sheets
• Precision hobby and model-making tasks
• Electronics enclosures and PCB component mounting (non-through-hole board drilling only if material and drill are compatible)
• Small repair jobs and fitting operations requiring tight-tolerance holes

Key specifications

• Shank type: straight cylindrical shank suitable for standard chucks
• Diameter: 1.5 mm
• Flute type: twist flute for chip removal
• Package: single piece in blister pack
• Intended use: standard drilling operations and pilot holes

How to use

Install the drill bit securely in the drill chuck, ensuring correct centring and firm clamping. Select an appropriate rotational speed for the material being drilled—lower speeds for harder metals and higher speeds for wood and plastics. Use light, steady pressure and allow the bit to do the cutting; withdraw periodically to clear chips when drilling deeper holes. For thin materials, support the workpiece to prevent deformation and achieve a clean exit. Wear suitable eye protection and follow general safe drilling practices.

Usage recommendations

For optimal results, match drill speed and feed rate to the material: slow for stainless or hardened metals, moderate for soft metals, and faster for wood and plastics. Use cutting lubricant when drilling metal to extend bit life and improve hole quality. Replace the bit if tip wear or chipping occurs to maintain hole precision.
