Drill bit set Proline 10804, twist bits, 2 pcs, length 100 mm

The Proline 10804 drill bit set contains two twist drill bits, each 100 mm in length, designed for general drilling tasks in materials compatible with twist bits. Supplied as a pair, these bits offer an immediate replacement option or the ability to equip multiple tools. The straight shank and conventional twist geometry make them suitable for use in handheld drills and drill presses where a 100 mm length is required.

Advantages

These Proline twist drill bits provide consistent cutting performance across common materials suitable for standard twist geometry. The matching pair reduces downtime by allowing quick replacement when one bit becomes dull. Their 100 mm length gives increased reach for deeper holes compared to shorter bits, while compatibility with standard drill chucks ensures easy installation and interchangeability.

Suitable for

• Drilling medium-depth holes in wood
• General-purpose drilling in plastics
• Light-duty drilling in soft metals where standard twist bits are appropriate
• Workshop and on-site drilling tasks requiring 100 mm bit length

Key specifications

• Bit type: twist (spiral) drill bits
• Quantity: 2 pieces
• Length: 100 mm per bit
• Shank: straight shank compatible with standard drill chucks
• Intended use: general-purpose drilling in materials suited to twist geometry

How to use

Fit the selected twist bit into the drill chuck and tighten securely before starting. Use appropriate drill speed for the material being drilled and apply steady pressure; allow the bit to cut without forcing. Withdraw the bit periodically to clear chips when drilling deeper holes. For threaded or fragile materials, use a pilot hole or backing support as needed. After use, clean chips and deposits from the flutes and store the bits in a dry place to prevent corrosion.

Usage recommendations

Match drill speed and feed rate to the material: lower speeds for metals, moderate speeds for plastics, and higher speeds for wood. Use cutting fluid when drilling metals to improve bit life. Replace or resharpen bits when cutting becomes inefficient or the hole quality degrades.
