Set of 6 snake drill bits 6-18mm for wood 460mm (SKU: G38121) – Professional set in a wooden box
Are you looking for a top-notch tool for precise, fast and extremely deep drilling in wood? The 6-piece professional wood auger drill set, 460 mm long (SKU: G38121), is an indispensable tool for carpenters, joiners, roofers and all DIYers who demand uncompromising precision in their work. This top-notch drill set allows you to easily drill deep holes in all types of wood without jamming or damaging the material.
Thanks to the special "snake" shape (spiral thread), the drill bits efficiently and quickly remove chips and sawdust from the hole, which prevents the tool from overheating and ensures smooth and clean hole edges. The entire set is stored in an elegant and durable wooden box, which protects the drill bits from damage and allows for easy transportation to the field.
Why choose a 460 mm long auger drill set?
When working with solid wood, beams or wooden structures, standard drill bits often do not reach the desired depth. This 46 cm long drill bit set solves this problem. Whether you are installing a roof, building a wooden arbor, a garden arbor or tackling complex carpentry projects, this set allows you to work quickly and accurately.
Each drill bit in the set is equipped with a 6-point mounting bracket (hex mount), which prevents the drill bit from slipping in the drill chuck, even under maximum loads. The extremely sharp cutting edges with a guide tip ensure that the drill bit starts drilling exactly where you want it, without prior scoring or slipping.

Frequently Asked Questions (FAQ) about the product
1. Are these drill bits suitable for use with regular cordless drills?
Yes, the drills have a standard 6-point (hexagon) mounting bracket that fits perfectly into most standard chucks on cordless and electric drills. However, due to the 460 mm length and drilling depth, we recommend using a more powerful drill with adequate torque, especially for larger diameters (16 and 18 mm).
2. How does the spiral shape (snake profile) help with drilling?
Snake drills have a deep, wide spiral that acts as a conveyor for the sawdust. When drilling deep, wood chips accumulate quickly; this design ensures that the sawdust is immediately pushed up out of the hole. This prevents the bore from clogging, reduces friction, prevents the drill from overheating, and allows for faster, smoother work.
3. How to properly maintain drill bits so they stay sharp for a long time?
After each use, clean the drill bits of any wood resin and sawdust. It is recommended to occasionally coat them with a mild rust-preventive oil. Always store the drill bits in the wooden box provided, as this prevents the cutting edges from rubbing against each other and possible damage during transport.

Instructions for using the product:
• Before use, check all 6 snake bits to make sure they are not bent, damaged or blunt.
• Select the appropriate drill bit diameter according to the required hole: 6, 8, 10, 12, 14 or 18 mm.
• Clamp the drill bit correctly in the drill and check that it is securely fastened.
• Secure the wooden workpiece securely so that it does not move while drilling.
• Mark the center of the hole and place the drill bit at the marked location.
• Start drilling at a moderate speed and guide the drill bit as perpendicular to the surface as possible.
• Do not apply excessive pressure while drilling; the threaded tip of the drill bit helps it to pull evenly through the wood.
• For deep holes, pull the drill bit out occasionally to remove wood chips.
• When drilling through the other side of the workpiece, reduce pressure to reduce the chance of tearing the wood.
• After finishing work, turn off the drill, wait until the drill bit has completely stopped, and remove it.
• Clean the drill bits and store them in a dry place.

Useful tips for work:
• The set contains 6 wood auger drill bits of various diameters, approximately 6–18 mm, with a length of 460 mm.
• The long version is suitable for deep holes in wood, especially in construction and carpentry work.
• The snake drill bit enables efficient removal of wood chips through a spiral groove.
• For larger diameters, use lower speeds and guide the drill steadily.
• When drilling through a complete piece of wood, you can use a backing piece of wood on the exit side to reduce tearing of the fibers.
• For accurate drilling, check the perpendicularity of the tool to the workpiece before starting.
• Do not use drill bits on metal, concrete or other materials for which they are not intended.
• After use, remove any shavings and check the sharpness of the tip and cutting edges.

Warnings:
• CAUTION – a long rotating drill bit can cause injury or kickback.
• Always wear safety glasses and, if necessary, hearing protection.
• Always secure the workpiece firmly. Do not hold it with your hand while drilling.
• Do not remove shavings with your hands, but with a brush or other suitable tool.
• Before changing the drill bit, turn off the drill and wait until it has come to a complete stop.
• Do not use twisted, cracked or damaged drill bits.
• Due to the length of 460 mm, pay attention to the stability of the tool and the possibility of the drill bit getting stuck.
• When drilling, do not wear loose clothing or jewelry that could get caught in the rotating part.
• Store drill bits in a dry place and out of the reach of children.

Same summary

The set of 6 snake drill bits with a diameter range from 6 to 18 mm and a length of 460 mm is useful primarily for home craftsmen and anyone who occasionally processes wood or performs installations in deeper areas. Due to the different dimensions, it is suitable for most basic DIY wood projects, where a longer length is also important for better reach. The set with such diversity makes work easier where it is necessary to frequently change drill bits or adjust holes to different needs. For very precise processing or for more demanding professional needs, it makes sense to consider specialized or shorter solutions.

Answers to frequently asked questions

Are these drill bits suitable for all types of wood?

Yes, the kit is intended for general drilling in softer and harder woods, but moderate use and caution are recommended when drilling hard tropical species to prevent blade wear.

Which electric drills are compatible with these drill bits?

The drills have a standard holder, so they are suitable for use with classic drills with a chuck that accepts shanks of the appropriate diameter.

Does longer drill bit length affect drilling accuracy?

Longer drill bits can slightly reduce accuracy if there is poor support or too much pressure, so we recommend stable clamping of the wood and even pressure.

Is every diameter in the set useful for furniture assembly?

Different diameters provide greater flexibility and cover the most common needs in furniture assembly and manufacturing, depending on the thickness of the screwed or connected elements.

What to do if the drill bit becomes blunt during work?

If you notice reduced cutting efficiency, carefully sharpen the drill bit on a whetstone or clean it to remove wood and resin residue.
