Broca Bosch 1,5 mm broca helicoidal 1 ud. – Modelo 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.

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.

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.
