Unique designed ground points and cutting edges drill faster,
cleaner holes, using less power than standard spade type
bits. Cut straight or angled holes in soft and hard woods,
plus formica, plaster, chipboard, foam core material, many
non-metallic building sidings and foam insulation. Made of
one-piece special heat treated tool grade steel. Six “flat”
1/4” shank fits securely in conventional chucks. Easy to spot
“size marking” is stamped on head. Bits also feature “head
hole” for convenient storage and wire pulling. Resharpenable
with saw file or grinder. Available individually or in sets.
Use in any rotary or rotary percussion drilling device for unexcelled
performance in brick, tile, granite, concrete, masonry and other similar
hard and dense materials. Brazed tungsten carbide tips have 120°
chamfer and are specially tempered for strength and long life.
Malco Step Drills actually deburr as they drill. Perfect for use as a “hole-opening” reamer. They can also be used for
making round holes from slots or intersecting holes. Made of industrial grade high speed steel. Malco Step Drills are
heat treated and tempered to assure maximum strength for long wearing rugged use. Completely resharpenable.
A unique double flute design assures the penetration of soft or thin
materials at the proper speed. Drill hole sizes from 1/8” to 1” in
sheet metal without burring or deforming stock or threading drill bit.
