Product Specifications:
This KAYA HSS twist drill bit is engineered for reliable hole making in a wide range of materials. The 118° point angle is the universal standard for steel and non‑ferrous metals, providing a strong cutting edge that resists chipping. With a 30° helix angle, chip evacuation is efficient for both shallow and medium‑depth holes. The bright finish leaves sharp, clean edges ready for immediate use.
The 5.20mm diameter sits between common 5.0mm and 5.5mm sizes – particularly useful for applications requiring a precise fit, such as dowel holes or pilot drilling for M6 taps (which typically call for a 5.0mm drill). Overall length of 70mm and flute length of 26mm qualify this as a standard jobber‑length drill, offering good rigidity for most CNC and manual drilling tasks.
Recommended cutting parameters: 20‑35 m/min cutting speed, 0.06‑0.12 mm/rev feed rate. Reduce speed when drilling stainless or heat‑treated alloys. Use cutting oil for best tool life in ferrous materials. For higher hardness or abrasive applications, consider our cobalt HSS or solid carbide lines. Custom coatings (TiN, TiAlN) and non‑standard lengths are available for OEM orders. Keep this versatile KAYA drill in your kit for everyday metalworking.
