Blue Demon 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.

A special grinding process produces superior cutting edges for faster drilling. PatentedBlue Demon Deflectors minimize bit plugging by formation cuttings.Use of high fluid volumes through a specially designed large water course gives speedy drillingthrough sticky clay and shale. Results - less recutting of the drilled formations and faster removalof cuttings from the hole.Unitized Step TypePartNumber DescriptionWeightEach (lbs.)ECU3173S 3 7/8" w/ 2 3/8 API 4.66ECU4003S 4" w/ 2 3/8 API 4.74ECU4113S 4 1/8" w/ 2 3/8 API 4.82ECU4123S 4 1/4" w/ 2 3/8 API 4.90ECU4143S 4 1/2" w/ 2 3/8 API 5.14ECU4163S 4 3/4" w/ 2 3/8 API 5.46Other sizes are available upon requestUnitized Chevron TypePart Number DescriptionWeightEach(lbs.)ECU3723C 3 7/8” Chevron w/ 2 3/8 API 5.02ECU4023C 4" Chevron w/ 2 3/8 API 5.10ECU4123C 4 1/8" Chevron w/ 2 3/8 API 5.18ECU4223C 4 1/4" Chevron w/ 2 3/8 API 5.26ECU4423C 4 1/2" Chevron w/ 2 3/8 API 5.50ECU4623C 4 3/4" Chevron w/ 2 3/8 API 5.82 ECU5734C 5 7/8" Chevron w/ 3 1/2 API 16.34ECU6034C 6" Chevron w/ 3 1/2 API 16.88ECU6134C 6 1/8" Chevron w/ 3 1/2 API 17.15ECU6234C 6 1/4" Chevron w/ 3 1/2 API 17.42ECU6434C 6 1/2" Chevron w/ 3 1/2 API 17.74ECU6634C 6 3/4" Chevron w/ 3 1/2 API 17.96Scratcher BitAvailable in 4" and 4 1/4 " Mayhew Jr. BoxBlue Demon large diameter drill bits file:///M:/WWW/blue%20Demon/Pg9-unitized-bit-forpdf.htm1 of 1 2/12/2009 4:39 PMStep Type blade bits are available in 3-way step designs. They are made to deliver maximum drilling penetration in soft to medium formations. The blades are forged from high quality steel and use heavy duty tungsten carbide inserts that are brazed in place with a superior silver alloy. Chevron Type bits are forged from high quality steel and use heavy duty tungsten carbide inserts that are brazed in place with a superior silver alloy.

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 protection. • No independent moving parts to become clogged. • Requires only a moderate weight for full effectiveness. • 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. Cutaway sketch of step drilling pattern as cut by Blue Demon BD and BDA Drill Heads. Lead bit drills 1½" hole. It is followed by other bits that shear and ream final hole size. Bits are set at an angle to assure fastest penetration without scaping, chipping or gouging . Left: Drilling blasthole with Blue Demon BDA Drill Head. 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. BDC-4 R-550CS conical bit The capped carbide is designed to maximize tool life 550 Puller 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 replaced with hammer punch (see below). BD-2 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 and tap lightly to seat.
