Shopping for Driver Bits and Mag Chucks

Spend your money wisely. Driver bits and mag chucks must be able to withstand impacts and repeated wear and tear. You want a product engineered for high-torque applications and heat-treated for hardness. The nature of the task will determine the right bit for the job. Consider these factors:

  • Desired diameter and depth of the hole
  • Material type
  • Type of drill you are using
  • Number and spacing of holes
  • Work environment and access

You will want to have the right bit on hand before starting a job.

Our Products

We work with leading manufacturers to deliver quality. This ensures everything you purchase from us can be counted on for performance. Available items include:

  • Driver bits: Among our bestselling products is the Makita 59-piece kit — a set of durable black phosphate-coated bits in popular sizes housed in a rugged ABS case. The SHOCKWAVE™ Impact Duty™ line of driver bits from Milwaukee features a custom steel alloy engineered to maximize resistance to wear and shock. Carefully optimized geometry for each tip type delivers up to 30 times longer life and three times more shock absorption.
  • Mag chucks: Mag chucks are bits, nutsetters and other drivers that are held in place by powerful rare-earth magnets. Compared to mechanical products, they offer multiple benefits, including faster changes between tools and greater ease-of-use — particularly when working outdoors or in busy environments. Bosch Impact Tough™ driver bits feature precision-engineered tips and heat-treated manufacturing to deliver strength and torque with less cam-out. Irwin Impact Performance Series™ products are notable for a unique lobular design that strips less and lasts longer.
  • Other products: In addition to standard driver bits and mag chucks, we also carry adapters, extensions and security bits. Many are universal but others can only be used with a particular tool. For detailed specifications and more information, visit individual product pages or contact a representative for more information.

Our inventory is constantly updated as we bring in innovative new products from top manufacturers, so check back often.
