Replaceable blades and rotary drag bits for water well, quarry, seismic, shallow oil and
gas, and construction applications, auger bits for vertical and horizontal drilling, and
directional pilot bits and reamers for horizontal boring.

Blue Demon Company was started in 1948 by Herb Hawthorne as the Hawthorne Bit
Company. It was the first company to develop a replaceable drag bit for use in drilling
waterwells, shallow oil and gas wells, and construction holes with a mud rotary drill rig.
They were awarded a patent for this product in 1948.

The company continued through the 1950’s and in 1960 the company was sold to Hughes
Tool Company where it remained a part of this company until 1987 when it was sold to
Sandvik Rock Tools. In 1992 the company was purchased by former employees of
Hughes and at that time the product name also became the company name.

The production facility was ultimately moved to Sedalia, Missouri where it continues to
produce the original replaceable blade bits, BD drill heads (originally developed by
Austin Powder), as well as directional pilot bits and replaceable backreamer bits which
we supply to numerous OEM’s and distributors.

Outside of our own product line we also produce carbide parts for a number of
manufacturers in allied businesses. If you have questions, don’t hesitate to contact us by
e-mail, phone or fax and we’ll be happy to assist you.

                                           BLUE DEMON UNITIZED BITS
                 Popular Blue Demon Unitized Insert Bits have high quality tungsten carbide inserts on all cutting
                 surfaces. A special grinding process produces superior cutting edges for faster drilling. Patented
                 Blue Demon Deflectors minimize bit plugging by formation cuttings.

                 Use of high fluid volumes through a specially designed large water course gives speedy drilling
                 through sticky clay and shale. Results - less recutting of the drilled formations and faster removal
                 of cuttings from the hole.

Blue Demon Auger Bits

           BD-1 SCRAPER BIT can be used in a variety of
           auger applications. The BD-1 is 17/8" wide.

           BD-3 has a 5/8" carbide and is designed to fit most
           common auger heads.

           BD-2 has a tapered shank that drive fits into the
           drill head without wedges or set screws. It can't
           wobble or work loose. BD-2 bits are easily
           replaced with hammer and punch.

           Blue Demon also produces two prong carbide
           auger bits that can be used as pilot bits or drilling
           tools in both vertical and horizontal drilling
           applications. We manufacture a 2”, 2 1/8”, 2 ¼”,
           and a 2 ½” with a 13/16” hex connection and a 3”,
           3 1/8”, and 3 3/16” with a 1 1/8” hex connection.

                           Blue Demon BDA Drill Head
The BDA brings all the advantages of the Blue
Demon BD to air drilling. It's a specially designed
tool that substantially increases penetration rates and
reduces costs in soft to medium rock formations.

When compared with ordinary drill heads with
rotating bits, the BDA will cut up to twice the
footage daily in soft shales, clays, shells, soft
limestone, red beds and other rocks of low
compressive strengths. In addition, it offers the
following important features:

   •   "Step" drilling pattern for fastest penetration.
   •   BD-2 Bits.
   •   Twin bits on outer surface for added
   •   No independent moving parts to become
   •   Requires only a moderate weight for full
   •   Precision machined head.
   •   Durable, trouble-free.
   •   6 sizes for drilling holes from 4½" to 1015/16".
   •   Choice of 23/8", 27/8", 3½" and 4½" API
       shanks. Other threaded shanks on request.

                           Blue Demon BDC Drill Head
The Blue Demon BDC Drill Head was
developed to drill in harder formation rock
with the same shearing action as our BD and
BDA Drill Heads. The BDC Drill Head
utilizes the same body, but with a round hole
to accept our R-550CS conical bit. This tool
comes with a sleeve retainer for maximum
holding power in the tool, but can be easily
removed from the head with our R-550 puller.
The capped carbide is designed to maximize
tool life even in the most abrasive conditions.
The BDC Drill Head is available in all the
same sizes as the BD and BDA Drill Heads
and can be made with hex, square, or API
threaded connections.

                 Blue Demon BD-2 Carbide Bit
     precision machined - extremely durable - easy to change
               BD-2 Carbide Bit

BD-2 Bit is precision machined to closest
possible tolerances for long, trouble-free
service. Its oversized carbide cuts
faster...never balls up...retains its original
effectiveness far longer.

Tapered shank of the BD-2 drive fits into the
drillhead without wedges or set screws. It
can't wobble or work loose. And, unlike
blade-type drill heads, BD-2 Bits are easily                               BD-2
replaced with hammer punch (see below).

BD-2 Bits can be replaced in seconds. Simply
place punch in hole beneath bit and tap with
hammer. Bit pops out. Then, insert new bit              Peaked carbide designed for tougher cutting
and tap lightly to seat.                                       conditions Specify BD-2LC

Directional Drilling - Pilot Bits

                                Chevron Carbide Bit

                    Designed for tougher drilling conditions in
                 medium hard formations such as caliche and shale

                          Carbide Impregnated Finger Bit

                  Carbide hardfaced fingers heat treated for long
                  life and faster penetration in clay, sand and soil.
                     Fingers peel clay where conventional cutters
                                        ball up

                               Step Type Carbide Bit

                      Excellent bit for toughness and abrasion
                  resistance in soft formations such as dirt, gravel
                                       and shale

                                     Tracker Bit

                  Newest pilot bit where carbides track each other
                  on opposite sides for maximum penetration and
                    faster cuttings removal in soft and medium

                               Serrated Carbide Bit

                        Bit is well suited to clay, sand, soils
                              and soft rock formations

                                   All Terrain Bit

                   soft as well as some medium rock formations

                                  Steep Taper HD

                 This bit is good in hard soils, soft rock and some
                    rock formations. It is designed for better

                                Steep Taper Conical

                 This bit is the same as Steep Taper HD except it
                 uses conical carbides instead of serrated carbide.

                               Heavy Duty (HD) &
                            Conical Heavy Duty (CHD)

                 “HD” bits utilize flat carbide along the side walls
                  of the pilot bit instead of hard facing to reduce
                  “CHD” bits utilize flat and conical carbides to
                      reduce wear and enhance cutting action.
