Product Description

 

Rail drill, also known as hollow drill, coring drill, is a special tool for railway track.
Rail drill is generally made of hard alloy and high speed steel series, which is used with rail drilling machine. The drill is welded with high strength hard alloy blade, which has the advantages of long drilling life, not easy to wear and tear, but also can be repaired and grinded several times after wear.
Rail drill is divided into high-speed steel series and carbide series, is used with rail drilling machine, is necessary for railway maintenance and maintenance of drilling tools, its characteristics of the use of a number of cutting edges, good wear resistance, high drilling precision, drilling efficiency than the ordinary twist drill doubled. A drill can drill 40-50 holes in the hardest material rail at a time, and the drill can be continuously polished for more than 10 times after wear; Another kind of carbide rail drill, the drill uses high strength carbide blade welding and become, drilling life is long, the blade should not wear, the drill should not fracture and other advantages, and wear can also be repaired several times.
1.Professional quality for efficient and fast hammer drilling in hard materials like concrete, granite, brick and other similar building materials.
2.Premium 40Cr steel with heat treatment improves core strength for maximum durability and extended life.
3.Hardened, premium carbide insert tip is strong and stays sharp longer for finer material break up and easier drilling.increases strength and durability.
4.Copper braze material gives high heat resistance for reduced tip loss,Carbide tip securely embedded in the steel body.
