We have lots of that siding here on houses built into the 60’s. I advise that it should not be sawn or drilled. The installers used shears and punches.

Asbestos Do’s And Don’ts For The Homeowner
- Do keep activities to a minimum in any areas having damaged material that may contain asbestos.
- Do take every precaution to avoid damaging asbestos material.
- Do have removal and major repair done by people trained and qualified in handling asbestos. It is highly recommended that sampling and minor repair also be done by asbestos professionals.
- Don’t dust, sweep, or vacuum debris that may contain asbestos.
- Don’t saw, sand, scrape, or drill holes in asbestos materials.
- Don’t use abrasive pads or brushes on power strippers to strip wax from asbestos flooring. Never use a power stripper on a dry floor.
- Don’t sand or try to level asbestos flooring or its backing. When asbestos flooring needs replacing, install new floorcovering over it, if possible.
- Don’t track material that could contain asbestos through the house. If you cannot avoid walking through the area, have it cleaned with a wet mop. If the material is from a damaged area, or if a large area must be cleaned, call an asbestos professional.
Major repairs must be done only by a professional trained in methods for safely handling asbestos.
Minor repairs should also be done by professionals since there is always a risk of exposure to fibers when asbestos is disturbed.
Doing minor repairs yourself is not recommended since improper handling of asbestos materials can create a hazard where none existed. If you nevertheless choose to do minor repairs, you should have as much information as possible on the handling of asbestos before doing anything. Contact your state or local health department or regional EPA office for information about asbestos training programs in your area. Your local school district may also have information about asbestos professionals and training programs for school buildings. Even if you have completed a training program, do not try anything more than minor repairs. Before undertaking minor repairs, carefully examine the area around the damage to make sure it is stable. As a general matter, any damaged area which is bigger than the size of your hand is not a minor repair.
If a renovation project requires fairly extensive work, it may be wise to call in a contractor. In this case, check into his experience in handling asbestos-containing materials, and discuss the preventive measures he plans to take.
Before undertaking minor repairs, be sure to follow all the precautions described earlier for sampling asbestos material. Always wet the asbestos material using a fine mist of water containing a few drops of detergent. Commercial products designed to fill holes and seal damaged areas are available. Small areas of material such as pipe insulation can be covered by wrapping a special fabric, such as rewettable glass cloth, around it. These products are available from stores (listed in the telephone directory under Safety Equipment and Clothing") which specialize in asbestos materials and safety items.
REMOVAL is usually the most expensive method and, unless required by state or local regulations, should be the last option considered in most situations. This is because removal poses the greatest risk of fiber release. However, removal may be required when remodeling or making major changes to your home that will disturb asbestos material. Also, removal may be called for if asbestos material is damaged extensively and cannot be otherwise repaired. Removal is complex and must be done only by a contractor with special training. Improper removal may actually increase the health risks to you and your family.
