Buying Guide for Professional Industrial Drill Bits

Industrial HSS drill bits for hard metals

Our selection of HSS (High Speed Steel) drill bits represents the benchmark in industrial drilling. These industrial drill bits offer exceptional heat resistance up to 600°C, allowing high cutting speeds without loss of hardness.

Polar Industrial Equipment's HSS industrial drill bits are heat-treated to ensure a life 3 times longer than standard drill bits. Ideal for steel, stainless steel, and non-ferrous alloys, they maintain their sharpness even after thousands of drillings.

Carbide technology for extreme performance

Carbide drill bits represent the ultimate evolution in industrial drilling bits. Made of tungsten carbide, these tools can withstand temperatures exceeding 800°C while maintaining their perfect geometry.

Our industrial carbide drill bits deliver cutting speeds 5 times faster than traditional HSS, significantly reducing production times. Lab tested: average life of 15,000 drills in hardened steel vs. 3,000 for a standard HSS drill bit.

Specialized geometries for each application

Each type of material requires a specific industrial drill bit geometry. Our industrial drill bits are available with helix angles from 15° to 40° depending on the application: low angle for hard and brittle materials, high angle for fast chip evacuation in soft materials.

Parabolic flute drills provide 40% more chip evacuation, essential for deep drilling. Our range includes 118°, 135°, and split-point tips for optimal penetration without pre-drilling.

High performance coatings

Modern coatings are transforming the performance of industrial drill bits. TiN (titanium nitride) increases tool life by 300% and enables cutting speeds up to 50% higher. TiAlN withstands extreme temperatures up to 900°C, making it ideal for dry machining.

Drill bits with DLC (Diamond-Like Carbon) coating offer a near-zero coefficient of friction, eliminating the need for lubrication in many applications.

Polar Industrial Equipment Technical Support and Warranty

Our expertise spanning over 30 years in the distribution of industrial drill bits allows us to offer unparalleled technical support. Each order benefits from personalized recommendations based on your materials and equipment.

Exclusive Guarantee: Immediate replacement for any drill bit that fails within the first 30 days. 24-hour express delivery in the Quebec City area for urgent orders. Contact us for urgent orders.

Frequently Asked Questions About Drill Bits and Drill Bits

How to choose the right blades and drill bits for my application?

Contact our technical experts for free. We analyze your materials, usage frequency, and precision needs to recommend the best accessories.

Difference between HSS and Cobalt drill bits

HSS bits work for standard metals (aluminum, mild steel).
Cobalt (M35) bits handle stainless steel and hard alloys, with better heat resistance and durability.

Best drill bit for reinforced concrete

Use an SDS-Plus carbide-tipped bit with at least 4 cutting edges.
A hammer drill is essential for efficient performance.

Why does wood split when drilling?

Use a 3-point wood bit to cut fibers cleanly.
Lower the speed at the end or place a backing board behind the piece.

What are the recommended drilling speeds?

Softwood: 1500–3000 RPM
Metal: 500–1500 RPM (with lubrication)
Concrete: 800–1200 RPM (hammer mode)

→ Larger diameters = lower speed to prevent overheating.

How to extend my drill bits’ lifespan?

Use proper speed, lubricate metals, avoid heat, and clean after use.
Sharpen HSS bits regularly with a bench grinder.

SDS bit stuck in chuck?

Pull back the locking sleeve while pulling the bit.

Clean the grooves and apply light oil to prevent jamming.

Can I use a metal bit on wood?

Technically yes, but it's not efficient — metal bits have the wrong cutting angle.

Always use wood bits for clean, fast results.

What are the meaning of markings (DIN 338, M35, HSS-G)?

DIN 338 = standard geometry
M35 = steel with 5% cobalt
HSS-G = precision ground high-speed steel

These markings ensure industrial-grade quality and performance.
