ريشة (لقمة) الثقب بوش قياس (12mm) المصنوعة من الفولاذ سريع القطع (HSS)

The Bosch HSS Drill Bit 12mm is a high-speed steel twist drill bit with a 12mm diameter designed for precision drilling in metal, wood, and plastic. It’s built for durability, sharpness, and clean, accurate holes, making it suitable for both DIY projects and professional tasks.

Key specs include: material – high-speed steel (HSS); diameter – 12mm; compatible with standard drill chucks; sharp cutting edges for clean holes; designed for heat and wear resistance to extend tool life; optimized for fast, smooth drilling across multiple materials.

This bit is versatile and suitable for drilling metal, wood, plastic, and PVC. For metal, use appropriate speed and lubrication to maximize life; for wood and plastic, drill at suitable speeds to avoid splinters or melting.

Open your drill’s chuck, insert the 12mm bit fully, and tighten securely. Mark your hole location, secure the workpiece, start with a light touch to create a guide, then apply steady pressure and maintain a straight, consistent feed until the hole is complete.

Avoid overheating by drilling at appropriate speeds and using cutting fluid or lubrication for metal. Clean away chips after use, store the bit in a dry place, and inspect the cutting edges regularly. If sharpening is needed, use proper sharpening methods for HSS bits.

Wear eye protection, clamp the workpiece securely, and keep hands away from the rotating bit. Use the correct speed for the material, apply steady pressure (don’t force it), and unplug the drill before changing bits.

Compared to smaller sizes like 10mm or 6mm, the 12mm bit creates larger holes and is ideal for bigger fasteners or pass-throughs. For a broader range of holes, you might consider a multi-size HSS bit set.

This bit is great for drilling holes in metal panels or profiles, wooden structural members that require larger diameter holes, and plastic or PVC components. It’s also useful when you need a larger hole for conduit, screws, or fittings in DIY or professional setups.

For metal, a pilot hole helps guide the bit and reduces wandering; for wood, a center punch or pilot hole improves accuracy and reduces splitting. For plastics, drill at a slower speed to minimize chipping and heat buildup.

Metal: use slower speeds and lubrication to manage heat; Wood: higher speeds with steady pressure for clean holes; Plastic: moderate speeds to avoid melting. In all cases, maintain a straight feed, back the drill out periodically to clear chips, and avoid applying excessive pressure that can dull or break the bit.

The Bosch 12mm HSS bit offers durable, long-lasting performance and reliable Bosch quality for frequent drilling tasks. If you need multiple sizes, a set often provides better per-bit value and flexibility for various jobs, while the single 12mm bit excels when you specifically need that diameter.
