Drill bit set Proline 10808, HSS, length 100 mm, 2 pieces

Proline 10808 is a set of two HSS drill bits, each 100 mm long, designed for general drilling tasks. The pair is supplied to provide a spare or duplicate bit for workshop and DIY needs. Constructed from high-speed steel (HSS), these straight shank drill bits are intended for use in compatible hand-held or bench drills and are suitable for drilling into a range of common materials when used with appropriate speeds and cutting fluids.

Advantages

The HSS material offers good hardness and heat resistance for standard drilling operations, while the 100 mm length allows deeper holes than short bits. Supplied as a two-piece set, it reduces downtime by providing an immediate replacement when one bit becomes worn or damaged. The uniform design of both bits ensures consistent hole size and reliable repeatability for small to medium tasks.

Suitable for

• Drilling holes in metal with correct drilling speed and cooling
• Drilling wood for joinery, fixtures, and furniture assembly
• Drilling plastic components and housings with controlled feed
• General workshop and home DIY projects requiring standard straight-shank bits

Key specifications

• Material: high-speed steel (HSS)
• Length: 100 mm
• Quantity: 2 pieces
• Shank type: straight shank for standard drill chucks

How to use

Fit the required bit securely in the drill chuck and clamp to prevent slipping. Select an appropriate drill speed and feed rate for the work material: lower speeds for harder metals, medium speeds for plastics, and higher speeds for most wood species. Use cutting fluid or lubricant when drilling metal to extend bit life and improve chip removal. Apply steady, even pressure—do not force the bit—and withdraw occasionally to clear chips on deep holes.

Usage recommendations

Inspect the bit before each use for signs of wear or damage. When drilling metals, use a suitable cutting fluid and moderate speed; when working with plastics, avoid excessive heat by using lower speeds and intermittent drilling. Replace worn bits promptly to maintain hole quality and reduce the risk of workpiece damage.
