If you want a straightforward, budget-friendly set of masonry bits you can keep on hand for common household drilling jobs, the amoolo 1/4" Carbide Tip Drill Bit Set includes 10 matching bits sized at 1/4" diameter and 4" length. It’s built around carbide tips for abrasion resistance and longer-lasting sharpness when drilling into tougher materials.

The design details are practical for DIY work: a U-type slot helps with dust removal, and the 3-flat shank is made to hold more securely in your drill chuck for steadier drilling. It’s intended for use with electric or cordless hammer drills across a wide range of materials—just note the explicit limitation: it cannot be used on tempered glass (such as car glass).

For best results, the manufacturer recommends cooling with water and controlling speed while drilling, then drying and/or applying oil afterward to help prevent rust.

  • 10-piece set of 1/4" diameter masonry drill bits (4" length)
  • Carbide tips designed for durability and abrasion resistance
  • U-type slot for faster dust removal during drilling
  • 3-flat shank for a tighter, more stable grip in the chuck
  • Multi-material use: tile, brick, cement, concrete, glass, plastic, cinder block, and wood (not for tempered glass)

Backed by a 90-day warranty for refund or replacement through the seller/manufacturer if you’re not satisfied.
