Bosch 2608595058 HSS-G DIN 338 Metal Drill Bit 3.5mm

DIN 338 defines the geometry and tolerance of metal drill bits to ensure consistent performance. For this bit, it means a standardized flute and tip design that provide reliable drilling in metal workpieces.

It’s suitable for a range of metals such as mild steel, stainless steel, aluminum, and copper. Avoid drilling very hard or hardened materials without the appropriate bit, and use cutting fluid to improve life and finish.

1) Secure your workpiece. 2) Insert the bit into a drill chuck and tighten securely. 3) Start at a low speed and gradually increase. 4) Apply steady, light pressure—let the bit cut rather than push. 5) Use cutting lubricant or coolant for metal drilling. 6) After drilling, remove chips and deburr if needed.

HSS-G offers a good balance of toughness, heat resistance, and cost for general metal drilling. It stays sharp longer on metals and handles higher temperatures than standard carbon steel bits, though it isn’t as hard as carbide for extremely hard materials.

3.5 mm diameter, HSS-G construction, DIN 338 standard, ground tip for faster cutting, rust-resistant coating, and compatibility with standard drills and drill presses.

Yes. It’s suitable for use in both drill presses and handheld drills. Ensure the chuck can hold the bit securely and that you clamp the workpiece to prevent movement.

Keep the bit cool with cutting fluid or oil, avoid high speeds that cause overheating, feed it steadily rather than forcing it, clean off chips after drilling, and store it dry to prevent rusting.

It’s primarily a drilling bit for metals. For spot drilling, you might use it to begin a hole, but for deburring, pair it with a deburring tool or accessory to finish holes neatly.

For different hole sizes, Fepy offers a range of DIN 338 HSS-G bits. For example: 4.0 mm variant: https://fepy.com/product/bosch-hss-g-din-338-metal-drill-bit-4-0mm; 2.5 mm variant: https://fepy.com/product/bosch-hss-g-din-338-metal-drill-bit-2-5mm; 6.0 mm variant: https://fepy.com/product/bosch-hss-g-din-338-metal-drill-bit-6-0mm. These allow you to choose the right diameter for your project and compare performance and price.

Fipy offers standard return options for eligible items. If you’re not satisfied, you can initiate a return within the applicable window and in accordance with the stated return conditions.

This bit uses a standard drill bit shank compatible with most hobby and professional drills. If your drill’s chuck accepts common small-diameter bits (which most do), it should fit. If you’re unsure, check your chuck’s maximum bit size and confirm compatibility with DIN 338 bits.
