The carbide drill bit manufacturing corporation HNCarbide concentrates on creating premium drilling products that match the needs of rugged application requirements while maintaining stable performance metrics. The knowledge about German drill bit specifications better enables users to decide which tool fits best into their chosen applications. The following blog examines how to select the proper drill bit supply through an exploration of DIN specifications together with drill bit geometries and material compositions and coating technologies.
Overview of German Drill Standards
The German Ministry sets stringent production requirements for carbide drill bits manufacturers need to meet for standardizing tool strength and durability. Established standards indicate which dimensions, geometries along with material properties create successful drilling efficiency. The following list includes the essential DIN industry standards that regulatory drill bit supply in Germany:
- The standard DIN 338 includes specifications regarding straight-shank twist drill bits while these tools commonly work with metalworking jobs. Both precision and durability represent strong characteristics of solid carbide drill bits.
- The specifications of deep drilling for center-point twist drill bits defined in DIN 345 guide industrial applications.
- DIN 6537 contains necessary specifications for concrete drill bits that need to deal with high-impact and abrasive conditions.
- Machine tools that use serious drilling operations must follow DIN 1412 standards for their Morse taper drill bits.
- DIN 8039 defines deep hole drill bits that primarily drill precise and extended holes in tough substances.
Each of these standards ensures that drill bit manufacturers produce tools capable of meeting the highest industrial demands.
Drill Bit Geometry and Design Requirements
Drill bit carbide tools experience performance effects as well as lifespan changes based on their geometric design features. Drill bit carbide tools must meet several important geometric requirements according to DIN standards.
Point Angle
Drill bit point angle directly determines both cutting effectiveness and the total sharpness of the drill. At the drill tip the point angle creates a boundary which modifies how the drill interacts with the surface material. Different drilling applications require different point angles between 118° to 140° that standard carbide drill bits normally provide. A 118° point angle specifically suits aluminum and wooden materials by easing penetration and minimizing the amount of cutting resistance. Using a 140° point angle becomes more beneficial when working on stainless steel or titanium alongside concrete materials since it secures tool stability while reducing wear and extending tool life.
Back Angle
How drill bits interact with surfaces depends on the size of their back angle also referred to as relief angle. The rotational angle controls material removal quantity during drilling so it directly impacts both cutting quality and tool operational lifespan. The right setup of back angle minimizes both friction and mechanical stress in solid carbide drill bits to prevent wear and avoid overheating during operation. A deficient back angle causes the tool to require excessive force whereas an excessively steep angle makes the cutting edge more vulnerable. Drill bits from Huana Tools carbide drill bits manufacturers arrive with pre-calculated back angle engineering that streamlines passage penetration and extends tool longevity in multifaceted uses.
Helix Angle
The cutting edge of drill flutes makes an angle with the drill axis to form the helix angle. The helix angle determines both chip clearance and drills how fast they work and their efficiency while cutting. When drilling metal subtypes including aluminum or plastics the optimal helical angle should be between 35° and 45° to generate fast chip removal while avoiding build-up inside flute structures. Both drilling performance and stability gain better results when the helix angle ranges between 10° to 30° during drilling stainless steel or cast iron. A proper helix angle selection leads to optimal drilling precision by reducing heat buildup and improving tool lifetime for drill bit carbide tools.
Flute Length and Core Thickness
The strength and efficiency of drill bits depend largely on their flutes and cores since both features directly impact their ability to function properly. The length of the flute controls the effectiveness with which chips escape from the drilling area. A drill’s shorter flutes achieve better rigidity than longer flutes for hard metal drilling whereas longer flutes work best during deep hole operations. The core thickness, or web thickness, impacts the strength of the drill bit. Drill bits with thick core diameters demonstrate superior strength and breakage-resistance properties thus becoming vital for performing deep drilling tasks in hardened steel materials. Industry-grade drill bit manufacturers from supply companies optimize both flute dimensions and core diameters according to specific machining requirements.
Comparison of German Drill Bit Standards
Each DIN standard caters to different applications. Below is a comparison of the key carbide drill bits standards:
