Why Source from The Kumar Mill Stores?
- Industrial Durability: We don’t do “disposable” tools. Our bits are sourced from top-tier manufacturers to ensure a longer lifespan and more holes per grind.
- Expert Curation: Not sure if you need a split-point or a spur-point? Our team has decades of technical expertise to guide you to the right geometry for your material.
- Bulk & Retail Availability: Whether you need a single 2mm bit or a thousand-piece industrial order, we maintain a deep inventory to keep your downtime to zero.
Pro Tip: Always match your drill speed (RPM) to the material. Harder materials like stainless steel require slower speeds and higher pressure to prevent “work hardening.”
