Key Features of Sealey HSS Drill Bits

Sealey HSS drill bits incorporate several distinctive features that enhance their performance and versatility. The high-speed steel construction provides excellent hardness and wear resistance, whilst maintaining sufficient toughness to resist fracture under normal drilling conditions. Many bits in the range feature split point geometries that reduce walking and enable accurate positioning without centre punching, particularly valuable when working on curved or angled surfaces.

The precision-ground flutes on Sealey HSS drill bits are designed to provide optimal chip clearance, preventing clogging and reducing heat build-up during extended drilling operations. This is particularly important when working with materials that produce continuous chips, such as mild steel and aluminium alloys. The 118-degree point angle used on standard jobber bits represents an excellent compromise between cutting efficiency and strength, suitable for the widest range of materials.

Sealey offers their HSS drill bits in various formats including fully ground options for enhanced accuracy, roll-forged variants for improved strength, and bright finished or titanium-coated versions for specific applications. Many sets come supplied in robust metal or plastic storage cases with clearly marked size indexes, making organisation and bit selection quick and convenient on busy worksites or in workshop environments.

Popular Sealey HSS Drill Bits

The Sealey range encompasses several popular configurations to suit different user requirements. Metric HSS drill bit sets typically cover the most commonly used sizes from 1mm to 13mm in 0.5mm increments, providing comprehensive coverage for general engineering and metalworking applications. These are often supplied in durable metal index cases that protect the bits and facilitate easy size identification.

Imperial drill bit sets cater to users working with older equipment, imported machinery, or specific industries where imperial measurements remain standard. Jobber length bits represent the most versatile option for general-purpose drilling, whilst stub length variants offer increased rigidity for precision work, and long series bits provide the extended reach required for deep hole drilling applications.

Sealey also offers specialist HSS drill bits including centre drills for precision location work, step drills for sheet metal applications, and countersink bits for preparing screw holes. Individual drill bits are available across the size range, allowing users to replace worn bits or expand existing sets with frequently used sizes.

Safety and Compliance

When using Sealey HSS drill bits, adherence to proper safety procedures is essential. Always wear appropriate personal protective equipment including safety glasses or goggles to protect against flying chips and swarf. Secure workpieces firmly using clamps or vices to prevent movement during drilling, and ensure that rotating drill bits are kept well clear of loose clothing, gloves, and long hair.

Select the appropriate drill bit size and type for the material being worked, and use correct drilling speeds according to the material specification – excessive speed can cause premature dulling or breakage, whilst insufficient speed may result in work hardening. Apply appropriate cutting lubricants when drilling metals to reduce heat build-up and extend tool life. Regularly inspect drill bits for wear, damage, or dullness, and retire any bits showing signs of deterioration.

Sealey HSS drill bits are manufactured to meet relevant British and European standards for quality and dimensional accuracy. Always follow the Health and Safety Executive (HSE) guidelines for safe operation of drilling equipment and ensure that workshop machinery is properly maintained and guarded in accordance with PUWER regulations.

Frequently Asked Questions

What materials can I drill with Sealey HSS drill bits?

Sealey HSS drill bits are suitable for drilling mild steel, cast iron, aluminium, copper, brass, other non-ferrous metals, hardwoods, softwoods, and most plastics. For harder materials such as stainless steel or tool steels, cobalt HSS bits or carbide-tipped options may be more appropriate.

What's the difference between bright finished and titanium-coated Sealey HSS drill bits?

Bright finished HSS drill bits are the standard option, offering excellent general-purpose performance. Titanium-coated (TiN) bits feature a gold-coloured surface treatment that reduces friction, increases hardness, and extends tool life, particularly beneficial when drilling tougher materials or when working without cutting lubricants.

How do I know when a Sealey HSS drill bit needs sharpening or replacing?

Signs that a drill bit requires attention include increased drilling pressure required, excessive heat generation, rough or oversized holes, squealing noises during cutting, or visible damage to the cutting edges. Properly maintained HSS bits can be resharpened several times using a drill bit grinder, though replacement is more cost-effective for smaller sizes.

Can Sealey HSS drill bits be used in cordless drills?

Yes, Sealey HSS drill bits work perfectly well in cordless drills, provided the drill has sufficient power for the material and hole size being attempted. For best results when using cordless tools, ensure the battery is fully charged, use sharp bits, and apply steady pressure without forcing, allowing the cutting edges to do the work.

What's the advantage of split point HSS drill bits over standard point designs?

Split point drill bits feature a modified point geometry that incorporates a small groove or web thinning at the tip. This design significantly reduces the tendency for the bit to wander when starting a hole, eliminates the need for centre punching in many applications, and requires less thrust force during initial penetration, resulting in more accurate hole positioning and faster drilling.
