MIBRO 871490 17-Piece Drill Bit Set

SKU CH-DC0K-NMPRM

17-piece set combines 12 titanium-coated HSS bits and 5 carbide masonry bits with 135° split-point tips and 3-flat shanks in a heavy-duty MBX case

  • Product colorTransparent
  • 17-piece set covers wood, metal and masonry drilling
  • 12 titanium-coated HSS bits with 135° split-point tips start on contact
  • 5 slow-spiral masonry bits with micro-grain carbide for brick and concrete
  • 3-flat shanks on all bits prevent chuck slippage
  • Heavy-duty MBX case with rubber corners protects bits from impact

Ideal set for home DIY drilling

This 17-piece handyman's set covers general-purpose drilling in all wood types, plastics, soft and mild metals, and most masonry. It combines 12 titanium-coated HSS jobber bits with 5 slow-spiral rotary masonry bits for versatile household tasks.

Coated bits and slow-spiral flutes change daily use

The 135° split-point tips on the HSS bits start on contact with less force and eliminate walking across the work surface. Masonry bits use premium micro-grain carbide with wide slow-spiral flutes that remove debris efficiently even in damp material.

Heavy-duty MBX case protects the investment

Molded rubber corners on the patented case absorb hard impacts during transport and storage. Both bit types feature 3-flat shanks that lock securely into the chuck, preventing slip under load. Not for buyers needing larger diameters or hammer-drill SDS shanks.

Questions about this item

How often will the titanium coating on the 12 HSS bits need replacement?

The titanium coating is a surface treatment that wears gradually with use; when cutting performance drops, the bits themselves are replaced rather than re-coated.

What limits continuous drilling with the 135° split-point tips before they overheat?

Heat buildup in the workpiece and bit is the first limit; using cutting fluid and clearing chips regularly lets the 135° split-point tips run longer without losing temper.

How much noise and heat do the 5 carbide masonry bits generate during all-day rotary drilling?

Rotary masonry drilling produces moderate vibration and dust rather than high noise; the carbide tips stay cooler than hammer-mode bits, and the slow-spiral flutes eject damp debris efficiently.
