Set of MODECO MN-60-904 HSS drill bits for metal with cylindrical shanks in sizes 2, 3, 4, 5, 6 and 8 mm. These high-speed steel (HSS) twist drills are intended for cutting holes in ferrous and non-ferrous metals and are suitable for use in workshops, maintenance and construction environments. The cylindrical shank design fits into standard chucks that accept round shanks and enables straightforward bit changes for portable drills and drill presses.
Advantages
The HSS material ensures good hardness and heat resistance during normal metal drilling operations, while the assortment of six common diameters covers a range of typical assembly and repair needs. Cylindrical shanks offer compatibility with many drill chucks without additional adaptations. The set provides consistent hole geometry for clean, accurate drilling in a variety of metal types.
Suitable for
- Drilling holes in sheet metal and plate
- Creating pilot holes for fasteners in assemblies
- Maintenance and repair tasks on machinery and vehicles
- General workshop and construction drilling where metal is involved
Key specifications
- Material: high-speed steel (HSS)
- Shank type: cylindrical (round) shank
- Included diameters: 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 8 mm
- Intended material: ferrous and non-ferrous metals
- Suitable for: portable drills and drill presses that accept cylindrical shanks
How to use
Select the drill bit diameter appropriate for the hole size and secure it in a chuck that accepts cylindrical shanks, ensuring it is held straight and tightened. Mark the drilling position and, where appropriate, use a center punch to prevent walking. Use cutting fluid or coolant when drilling thicker or harder metals to reduce heat and prolong bit life. Start drilling at low speed to establish the hole, then adjust speed and feed according to the metal type and bit diameter, applying steady pressure without forcing.
Usage recommendations
For best results, use appropriate cutting fluid when working with stainless steel or other hard alloys, clamp the workpiece securely, and back the drill through the hole carefully to avoid burrs. Replace worn bits to maintain hole accuracy and prevent damage to the workpiece or tool.
