رؤوس الثقب من (Bosch) قياس (4MM) و المصنوعة من الفولاذ سريع القطع (PTW2608595059)

HSS-G construction, 4 mm diameter, precision-ground tip, long-lasting sharpness, reduced wear, optimized drilling speed, and versatility across metal, wood, and plastic.

Insert the bit into your drill's chuck and tighten securely. Use appropriate speed for the material (slower for metal, faster for wood). Mark the hole, start with light pressure, and consider a center punch to prevent wandering. For metal drilling, use a suitable cutting fluid or lubrication and periodically clear chips. After drilling, release the trigger and remove the bit carefully.

Metal, wood, and plastic are suitable materials. The bit is designed for versatility across these common substrates, delivering clean holes with good control.

This Bosch HSS-G drill bit combines precision-ground geometry with robust HSS-G construction for reliable performance across metal, wood, and plastic. For comparison, you can consider other 4 mm options such as Bosch 4 mm variants and alternative brands available on Fepy, including the 3 mm and 5 mm Bosch HSS-G bits and DeWalt 4 mm options (all available on Fepy): - Bosch HSS-G 3 mm: https://fepy.com/product/bosch-hss-g-drill-bit-3mm - Bosch HSS-G 5 mm: https://fepy.com/product/bosch-hss-g-drill-bit-5mm - DeWalt HSS-G 4 mm: https://fepy.com/product/dewalt-hss-g-drill-bit-4mm

Yes, it is designed to fit standard drill chucks that can grip a 4 mm diameter shank. Ensure your chuck can securely clamp a 4 mm bit and avoid forcing the bit into a chuck that cannot grip it firmly.

Use appropriate cutting fluid or lubrication when drilling metal, avoid excessive feed pressure, drill at recommended speeds for the material, periodically clear chips, and keep the bit sharp by using proper sharpening or replacing when worn. Store the bit in a dry place to prevent corrosion.

Wear eye protection and, if needed, gloves. Secure the workpiece with clamps, tie back long hair, avoid loose clothing, and keep hands away from the rotating bit. Use the correct speed for the material and never try to push the bit; let the bit do the cutting with controlled pressure.

Yes. The Bosch HSS-G 4 mm bit combines durable construction, precision-ground edges, and versatility across multiple materials, delivering reliable performance and longer life for both DIY and professional use.

If you’re exploring options, you can check these nearby alternatives on Fepy: - Bosch HSS-G 3 mm: https://fepy.com/product/bosch-hss-g-drill-bit-3mm - Bosch HSS-G 5 mm: https://fepy.com/product/bosch-hss-g-drill-bit-5mm - DeWalt HSS-G 4 mm: https://fepy.com/product/dewalt-hss-g-drill-bit-4mm

For beginners, start by selecting the appropriate speed for your material, secure your workpiece, and practice with a scrap piece. Use light initial pressure, keep the bit cool with lubrication when drilling metal, and gradually increase feed as the bit begins to cut smoothly.

The precision-ground tip helps start holes accurately and reduces wandering, leading to cleaner holes with less walking and better control, especially when drilling in harder materials like metal.
