DISSTON COMPANY

DISSTON COMPANY 282913 4 Piece Glass & Tile Carbide Tipped Drill Bit Set

SKU CH-7R55-VZK4J

Four carbide-tipped bits drill clean holes in glass, tile, marble and mirrors with reduced breakout

  • Drill clean holes in glass and tile with carbide tips that resist wear
  • Four bit sizes cover common tasks from 1/8" to 5/16
  • Spear-pointed tips reduce breakout when drilling through from one side
  • Standard shank fits any 3/8" drill press or variable-speed drill
  • Zinc finish protects bits against corrosion during storage and use

4-piece carbide drill bit set

The Disston Company 282913 set contains four carbide-tipped bits sized 1/8", 3/16", 1/4" and 5/16". Each bit has a spear-pointed tip designed to reduce breakout when drilling through hard, brittle surfaces. The standard shank fits any 3/8" drill press or variable-speed drill. A zinc finish adds corrosion resistance for workshop storage.

Suited to tile, glass and marble work

This set is aimed at DIYers and tradespeople who need clean holes in ceramic tile, mirrors, glass, marble, Vitrolite or china. It is not intended for metal, masonry, concrete or wood where different tip geometries are required. Buyers who need larger diameters or a wider range of sizes should look at something else.

Four sizes cover common anchor and fixture holes

The 1/8" to 5/16" range handles typical pilot holes for brackets, towel rails and light fixings in tile or glass. Carbide tips stay sharp longer than steel in abrasive materials, giving a usable life across multiple jobs. The set runs out when holes larger than 5/16" are specified or when the material demands a diamond core bit instead.

Questions about this item

What size drill chuck is required to hold the standard shank on these bits?

A 3/8" chuck on a variable-speed drill or drill press will hold the standard shank supplied with each bit in the set.

Will the spear-pointed tip still reduce breakout when I drill through glazed ceramic tile that is harder than the examples listed?

The spear-pointed tip is designed to reduce breakouts when drilling from one side to the other in ceramic tile, mirrors, glass, marble, Vitrolite and china.

How can I confirm the bits are cutting cleanly after I start drilling?

A clean, chip-free hole edge and steady progress without the bit wandering show the carbide tips are working as intended.
