Why customers choose TaskHolt Tools

Overview

RCINDUS presents a 20-piece 9/64 inch cobalt drill bits set designed to elevate your metalworking and general drilling projects. Built for durability and consistent starts, this collection aims to help you complete tasks efficiently while maintaining control over the workflow.

Why choose RCINDUS 9/64" Cobalt Drill Bits

These bits pair M35 high-speed steel with 5% cobalt, a combination that can resist heat and maintain sharp edges through repeated drilling. While no tool can guarantee outcomes, the composition is engineered to perform under demanding conditions and provide dependable performance when facing tougher materials.

  • 20-piece pack with a plastic storage case for organized storage between jobs.
  • 135-degree self-centering split-point design to help prevent walking and start holes accurately on hard surfaces.
  • Versatile across hardened metal, stainless steel, cast iron, as well as plastic, PVC board, and wood.
  • Diameter accuracy controlled within -0.03 mm, reflecting careful manufacturing processes.

What’s included and how to use

This set covers a range of common drilling tasks, with a 9/64 inch diameter that fits typical pilot holes and small-hole needs. For best results, secure the workpiece, apply steady pressure, and choose an appropriate speed. If needed, use light lubrication to manage heat buildup and prolong bit life.

  • Keep bits protected in the supplied plastic case to maintain organization and prolong tool life.
  • Match speed and feed to the material type to minimize heat and maximize edge retention.

Application highlights

Suitable for projects involving hardened metal, stainless steel, cast iron, plus non-metal materials like plastic, PVC, and wood. The split-point tip helps with clean starts, while the cobalt-enhanced alloy offers robustness for longer tool life in challenging workpieces. The set’s factory-made quality emphasizes reliable geometry and consistent performance across tasks.
