Product Specifications:
This HSS twist drill bit is a solid everyday choice for drilling holes in carbon steel, soft alloy steel, and non‑ferrous metals. The 118° point angle is the standard for steel and aluminum, providing a durable cutting edge. With a 30° helix, chip evacuation is efficient for shallow to medium depths. The bright finish delivers sharp edges right out of the box.
The 6.7mm diameter is a slightly oversized alternative to the common 6.5mm – useful when a looser fit or a specific fastener clearance is required. Total length 80mm and flute length 31mm make this a standard jobber‑length drill, offering good rigidity for CNC and manual drilling tasks. For harder materials like stainless steel, reduce speed and use cutting oil.
Recommended cutting parameters: 20‑35 m/min cutting speed, 0.08‑0.15 mm/rev feed. For best tool life, always use external coolant or lubrication. Custom coatings (TiN, TiAlN) and non‑standard lengths are available for OEM orders. Keep this versatile 6.7mm drill in your kit for everyday metalworking needs.
